SG1577 General Description

The SG1577 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 feedbac.
