ACT410 rev 3, 27-feb-14 innovative power tm - 7 - www.active-semi.com copyright ? 2014 active-semi, inc. active-semi proprietary D for authorized recipients and customers activepsr tm is a trademark of active-semi. ACT410 is a high performance peak current mode low-voltage pwm controller ic. the controller includes the most advance features that are required in the adaptor applications up to 36 watt. unique fast startup, frequency fold back, qr switching technique, accurate olp, low standby mode operation, external compensation adjustment, short winding protection, ocp, otp, ovp and uvlo are included in the controller. startup startup current of ACT410 is designed to be very low so that vdd could be charged to v ddon threshold level and device starts up quickly. a large value startup resistor can therefore be used to minimize the power loss yet reliable startup in application. for a typical ac/dc adaptor with universal input range design, two 1m ? , 1/8 w startup resistors could be used together with a vdd capacitor(4.7uf) to provide a fast startup and yet low power dissipation design solution. during startup period, the ic begins to operate with minimum ippk to minimize the switching stresses for the main switch, output diode and transformers. and then, the ic operates at maximum power output to achieve fast rise time. after this, v out reaches about 90% v out , the ic operates with a ?soft-landing? mode (decrease ippk) to avoid output overshoot. constant voltage (cv) mode operation in constant voltage operation, the ACT410 senses the output voltage at fb pin through a resistor divider network r5 and r6 in figure 2. the signal at fb pin is pre-amplified against the internal reference voltage, and the secondary side output voltage is extracted based on active-semi's proprietary filter architecture. this error signal is then am plified by the internal error amplifier. when the secondary output voltage is above regulation, the error amplifier output voltage decreases to reduc e the switch current. when the secondary output voltage is below regulation, the error amplifier output voltage increases to ramp up the switch current to bring the secondary output back to regulation. the output regulation voltage is determined by the following relationship: where r fb1 (r5) and r fb2 (r6) are top and bottom feedback resistor, n s and n a are numbers of transformer secondary an d auxiliary turns, and v d is the rectifier diode forward drop voltage at approximately 0.1a bias. constant current (cc) mode operation when the secondary output current reaches a level set by the internal current limiting circuit, the ACT410 enters current limit condition and causes the secondary output volta ge to drop. as the output voltage decreases, so does the flyback voltage in a proportional manner. an internal current shaping circuitry adjusts the switching frequency based on the flyback voltage so that the transferred power remains proportional to the output voltage, resulting in a constant secondary side output current profile. the energy transferred to the output during each switching cycle is ?(lp ilim^2) , where lp is the transformer primary i nductance, ilim is the primary peak current, and is the conversion efficiency. from this form ula, the constant output current can be derived: where f sw is the switching frequency and v outcv is the nominal secondary output voltage. the constant current operation typically extends down to lower than 40% of nominal output voltage regulation. standby (no load) mode in no load standby mode, the ACT410 oscillator frequency is further reduced to a minimum frequency while the current pulse is reduced to a minimum level to minimize standby power. the actual minimum switching frequency is programmable with an output preload resistor. loop compensation the ACT410 allows external loop compensation by connecting a capacitor and a resistor to extend its applications, especially with different v out in a wide output power range. primary inductance compensation the ACT410 integrates a built-in primary inductance compensation circuit to maintain constant olp despite variations in transformer manufacturing. the compensated ranges is +/-7%. primary inductor current limit compensation the ACT410 integrates a primary inductor peak functional description (1) d a s 2 fb 1 fb outcv v n n ) r r 1 ( v 20 . 2 v - + = ) v f ( ) r v ( l 2 1 i outcv sw 2 cs cs p outcc = (2)

ACT410 is able to achieve very accurate olp (constant i out ) independent of input lines and primary inductor values. short circuit protection when the secondary side output is short circuited, the ACT410 enters hiccup mode operation. this hiccup behavior continues until the short circuit is removed. functional description cont?d vdrain_gnd mosfet t dc voltage t ton possible valley turn on protection functions failure condition protection mode v dd over voltage v dd > 20.5v (4 duty cycle) auto restart over temperature t > 135 ? c auto restart short winding/ short diode v cs > 1.75v auto restart over load ipk = i limit auto restart output short circuit v fb < 0.56v auto restart open loop no switching for 4 cycle auto restart v cc under voltage v cc < 6.8v auto restart vfb over voltage v fb > 3v (4 duty cycle) auto restart
