The SC1102 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. Synchronous operation allows for the elimination of heat sinks in many applications. The SC1102 is 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, al- lows the use of inexpensive N-channel power switches. SC1102 features include temperature compensated voltage reference, triangle wave oscillator and current sense comparator circuitry. Power good signaling, shutdown, and over voltage protection are also pro- vided. The SC1102 operates at a fixed 200kHz, providing an optimum compromise between efficiency, external component size, and cost.
