Overview
SC1102/SC1102A Synchronous Voltage Mode Controller for Distributed Power Supply Applications POWER MANAGEMENT Description Features The SC1102 and SC1102A are low-cost, full featured, synchronous voltage-mode controllers designed for use in single ended power supply applications where efficiency is of primary concern.
Synchronous operation allows for the elimination of heat sinks in many applications.
The SC1102s are ideal for implementing DC/DC converters needed to power advanced microprocessors in low cost systems, or in distributed power applications where efficiency is important.
Internal level-shift, high-side drive circuitry, and preset shoot-thru control, allows the use of inexpensive N-channel power switches.
SC1102s features include temperature compensated voltage reference, triangle wave oscillator and current sense comparator circuitry.
Power good signaling, shutdown, and over voltage protection are also provided.
The SC1102 operates at a fixed frequency of 200kHz and the ...
