SC1102EVB中文资料先之科数据手册PDF规格书

描述 Description

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.
