The APW7061is a voltage mode, synchronous PWM controller which drives dual N-channel MOSFETs. It integrates the controls, monitoring and protection functions into a single package, which provides one controlled power outputs with under-voltage and over-current protections. APW7061 provides excellent regulationfor output load variation. An internal 0.8V temperature-compensated reference voltage is designed to meet the various low output voltage applications. A power-on-reset (POR) circuit limits the VCC minimum opearting supply voltage to assure the controller working well. Over current protection is achieved by monitoring the voltage drop across the low side MOSFET, eliminating the need for a current sensing resistor and short circuit condition is detected through the FB pin. The over-current protection triggers the soft-start function until the fault events be removed, but Under-voltage protection will shutdown IC directly. Pull the COMP pin below 0.4V will shutdown the controller, and both gate drive signals will be low.
