The SG1577A is a high-efficiency, voltage-mode, dualchannel, synchronous DC/DC PWM controller for two independent outputs.

The two channels are operated out of phase.

The internal reference voltage is trimmed to 0.7V±1.5%.

Integrated Two Sets of MOSFET Drivers Two Independent PWM Controllers Constant Frequency Operation: Free-running Fixed Frequency Oscillator Programmable: 61kHz to 340kHz Maximum Input Supply Voltage: 15V Programmable Output as Low as 0.7V Internal Error Amplifier Reference Voltage: 0.7V±1.5% Two Soft-Start / EN Functions Programmable Over-Current Protection (OCP) 30V HIGH Voltage Pin for Bootstrap Voltage Output Over-Voltage Prote.
