Semtech Corporation SC1102
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. 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. The SC1102 operates at a fixed frequency of 200kHz and theAPPLICATIONS
POWER MANAGEMENTDESCRIPTION
FEATURES
Synchronous operation allows for the elimination of heat sinks in many applications. 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.
