SC1157 Product details

Description

The SC1157 is a low-cost, full featured, synchronous voltage-mode controller designed for use in single ended power supply applications where efficiency is of primary concern.

Features

include an integrated 4-bit VID DAC, temperature compensated voltage reference, triangle wave oscillator, current limit comparator, frequency shift over-current protection, and an internally compensated error amplifier. The SC1157 operates at a fixed 140KHz, providing an optimum compromise between efficiency, external component size, and cost.
