SG1577A Datasheet - Fairchild Semiconductor

SG1577A Dual Synchronous DC/DC Controller

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%. It is connected to the error amplifier’s positive terminal for voltage feedba.

SG1577A Features

* 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
