7 ? 2006 semtech corp. www.semtech.com power management sc600 applications information regulated fractional charge pump operation a fractional charge pump is a voltage converter which implements switched capacitor techniques to produce an output voltage that is one of several multiples of the input voltage. regulated fractional charge pumps (also called charge pump regulators) use a linear regulator with vari- ous charge pump con gurations to deliver a regulated out- put over a wide input voltage range. regulated fractional charge pumps have improved ef ciency over ordinary lin- ear regulator and charge pump circuit combinations. the improved ef ciency is achieved by implementing multiple charge pump con gurations on one integrated circuit. the correct charge pump con guration is automatically selected to meet the regulation requirements at the best possible ef ciency. the sc600 has three charge pump con gurations (modes), which multiply the input voltage by 1x, 1.5x and 2x. the charge pump con gurations are implemented with two switched or 'bucket' capacitors plus the input and out- put capacitor. the bucket capacitors are con gured for 1x mode at start-up to source current to the output capacitor and bring the output up quickly. the charge pump will begin switching in 1.5x mode. during normal operation, starting with a fully charged li-ion cell, the battery voltage will begin at about 4.1v. as the battery discharges and the voltage decays, the sc600 will eventually transition to 2x mode when the battery voltage is approximately 3.50v. hysteresis is provided to prevent mode toggling. the out- put is prevented from exceeding 6.0v. this feature allows the use of 6.3v ceramic capacitors. mahxlife tm advantage the plot on page 1 shows the ef ciency of the sc600a. an example of a 5.0v regulated charge pump doubler is plotted to demonstrate how effective the sc600?s 1.5x mode is at improving ef ciency when the input voltage is above 3.5v. most of the li-ion battery life is above 3.5v where the sc600 achieves more than 20% higher ef - ciency compared to the 5.0v regulated charge pump dou- bler with only a 2x mode. following the ef ciency curve from left to right as the battery discharges, the sc600a 5.0v remains in 1.5x mode until 3.5v and then transitions to 2x mode. component versions there are four versions of the sc600. the component selection table on page 4 highlights the differences be- tween the component types. the three basic differences between the component versions are in the output volt- age, maximum output current capability, and the mode transition point. the mode transition point is the value of input voltage at which the component will transition between 1.5x and 2x modes. 5.0v, 4.5v, and 4.0v versions are available. the sc600a (5.0v) is most ef cient for applications that use up to 60ma. the sc600b (4.5v) and sc600c (4.5v) have different maximum output currents and mode transition points. the lower mode transition point of the sc600c allows it to remain in 1.5x mode longer for greater power savings. the sc600b has higher output capability, up to 120ma, and s600c is rated for 60ma. the sc600d (4.0v) is for applications using up to 120ma. start-up conditions typical start-up time is less than 50 s. caution: the sc600 must be enabled while 650khz or 262khz is selected to pre- vent over-voltage during start-up. led bias and backlighting applications when using the sc600 for led bias, note that the sc600c and sc600d require the same input power per unit of output current even though the sc600c is more ef cient. also, the sc600a will have the same input power as the sc600b though the sc600a is more ef cient. the following plots of input power vs. input voltage high- light the differences in application of the four component versions. to achieve the lowest possible input power, it is desirable for the charge pump to remain in 1.5x mode until the input voltage is as low as possible. the transi- tion points from 1.5x to 2x are identi ed in the plot where the input power steps upward as the input voltage moves lower.

10 ? 2006 semtech corp. www.semtech.com power management sc600 applications information (cont.) comparison with other regulation methods in many instances, a charge pump regulator is the best choice for portable power applications. these regulators offer many advantages over switch mode regulators. a smaller bill of materials, less layout area, lower compo- nent height, less noise, no emf, and less overall circuit cost are typical reasons to use this type of regulation. in some cases the ef ciency of a charge pump regulator ex- ceeds the ef ciency of a switch mode regulator. inductors are often the largest and most expensive dis- crete component in a design. because there are no in- ductors used in the sc600, cost, noise, layout area, as well as the the emf associated with the inductor, are eliminated. the sc600?s xed frequency harmonics are an advantage in portable communications equipment, such as cellular telephones. the sc600 has distinct frequencies of op- eration, so the harmonics are predictable. the harmonics are not xed in a switch mode regulator. ripple performance examples of the output ripple, charge pump frequency and capacitor size are listed in table 2. switch mode regulators have harmonics which vary due to the pulse width modulation used to regulate the output. varying harmonics can make it dif cult to ensure accept- able noise performance over the entire operating range. many switch mode regulators have increased voltage rip- ple on the output during pulse skipping mode due to large periods of time when no current is supplied to the output. the sc600 supplies current to the output continuously, so the voltage ripple is less than a switch mode regula- tor, even with greatly reduced output capacitance. the sc600 delivers a continuous current to the output during 1x, 1.5x and 2x modes. most of the battery life requires 1.5x mode. frequency selection cx8 and cd4 are frequency select inputs; input from a p or other device may be used to change the charge pump frequency at any time (as shown in table 1). the opti- mal frequency will depend upon the capacitor values, the load current, and the acceptable amount of output ripple. lower frequencies will be more ef cient, while higher fre- quencies will support higher output currents with lower ripple. y c n e u q e r f g n i h c t i w s8 x c4 d c z h k 2 300 z h k 801 z h k 2 6 210 z h k 0 5 611 t able 1 -frequency selection logic . o n t r a p] z h k [ . q e r fi t u o ] a m [] p - p v m [ e l p p i r t u p t u o e d o m x 5 . 1 ] p - p v m [ e l p p i r t u p u o e d o m x 2 c t u o ] f [c t e k c u b ] f [ v 0 . 5 a 0 0 6 c s 85 5 65 111 2 30 20 5 15 211 2 6 20 65 20 211 0 5 60 60 15 111 0 5 60 60 25 23 3 . 01 t able 2 -ripple p er formance
11 ? 2006 semtech corp. www.semtech.com power management sc600 applications information (cont.) mode transition impedance the mode transition impedance ro refers to the output resistance of the charge pump before a transition to a stronger mode occurs. ro is dependent upon the frac- tional charge pump, switching frequency, bucket capaci- tor value, bucket capacitor esr, and the internal switch resistances. ro is proportional to, 1 fc ? ro can be measured to verify a low transition imped- ance. before measuring ro, select the capacitors, set the operating frequency and a constant load current. find the input voltage just before a weak to strong mode tran- sition (i.e., 1.5x to 2x mode). measure v in , v out , and i out before the transition. ro will be, ro= mode v in ? v out i out t able 2 -ripple p er formance (cont.) . o n t r a p] z h k [ . q e r fi t u o ] a m [] p - p v m [ e l p p i r t u p t u o e d o m x 5 . 1 ] p - p v m [ e l p p i r t u p u o e d o m x 2 c t u o ] f [c t e k c u b ] f [ b 0 0 6 c s ) 1 ( v 5 . 4 80 15 1 20 511 2 30 40 0 30 911 2 6 20 2 10 45 211 0 5 60 2 15 15 211 0 5 60 2 10 35 43 3 . 01 v 0 . 4 d 0 0 6 c s 80 15 0 10 511 2 30 40 4 25 411 2 6 20 2 10 30 211 0 5 60 2 11 10 211 0 5 60 2 15 20 43 3 . 01 note: (1) sc600c is very similar to sc600b. a lower value of ro will improve efficiency, so low esr ceramic capacitors are required. an x7r or x5r dielec- tric is recommended. y5v dielectric can require 2 to 3 times the rated value of an x7r dielectric for the same performance over the operating temperature range. efficiency efficiency for the sc600 is defined as, = v o i o ? v in mode i o ? i q ?
