  1 tm fn4029.5 hip5010, HIP5011 7v, 17a synchrofet? complementary drive synchronous half-bridge designed with the p6 and pentium? in mind, the intersil synchrofet? family provides a new approach for implementing a synchronous rectified buck switching regulator. the synchrofet replaces two power dmoss, a schottky diode, two gate drivers and synchronous control circuitry. the complementary drive circuit turns the upper fet on and the lower fet off when the input from the pwm is high. when the input from the pwm goes low the upper fet turns off and the lower fet turns on. the HIP5011 has a pwm pin that inverts the relationship from the input to phase. this architecture allows the designer to utilize a low cost single-ended pwm controller in either a current or voltage mode configuration. the synchrofet operates in continuous conduction mode reducing emi constraints and enabling high bandwidth operation. several features ensure easy start-up. first, the supply currents stay below specification as the supply voltages ramp up; no unexpected surges occur that might perturb a soft-start or deplete a charge-pump. second, any power-up sequence of the v cc , v in , or pwm pins can be used without causing large currents. third, the chip operates when v cc is greater than 2v so v cc can be created from a charge pump powered from v in . features ? complementary drive, half-bridge power nmos ? use with low-cost single-output pwm controllers ? improve efficiency over conventional buck converter with schottky clamp ? minimum deadtime provided by adaptive shoot-through protection eliminates external schottky ? grounded case for low emi and simple heatsinking ? low operating current ? frequency exceeding 1mhz ? dual polarity input options ? all pins surge protected applications ?5v to 3.3v synchronous buck converters ? pentium and p6 power supplies ? powerpc ? power supplies ? bus terminations (btl and gtl) ? drive 5v motors directly from microprocessor typical application block diagram pentium? is a registered trademark of intel corporation. powerpc? is a trademark of international business machines. synchrofet? is a trademark of intersil corporation. pinouts hip5010is1, HIP5011is1 (sip - vertical) top view hip5010is, HIP5011is (sip - gullwing) top view 1 phase 2v in 3v cc 4 5 pwm (hip5010), pwm (HIP5011) 6v in 7 phase gnd (tab) front rows = pins 1, 3, 5, 7 back rows = pins 2, 4, 6 1 phase 2v in 3v cc 4 5 pwm (hip5010), pwm (HIP5011) 6v in 7 phase gnd (tab) ordering information part number temp. range ( o c) package pkg. no. hip5010is -40 to 85 7 ld gullwing sip z7.05b hip5010is1 -40 to 85 7 ld staggered vertical sip z7.05c HIP5011is -40 to 85 7 ld gullwing sip z7.05b HIP5011is1 -40 to 85 7 ld staggered vertical sip z7.05c +12v +3.3v phase pwm v in v cc control +5v hip5010 pwm controller synchronous rectified buck converter gnd data sheet march 1996 caution: these devices are sensitive to electrostatic discharge; follow proper ic handling procedures. 1-888-intersil or 321-724-7143 | intersil (and design) is a trademark of intersil americas inc. copyright ? intersil americas inc. 2002. all rights reserved
