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
