Description

The AP2002 is a low-cost, full featured, and  synchronous voltage-mode controller designed for use in single ended power supply applications where efficiency is of primary concern. Thissynchronous operation allows the elimination of heat sinks in many applications. The AP2002 is ideal for implementing DC/DC converters that is needed for the 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.

AP2002 features include temperature compensated voltage reference, an internal 200Khz virtual frequency oscillator, under voltage lockout protection, soft-start function and current sense comparator circuitry. Power good signaling, shutdown, and over voltage protection are also provided by AP2002.
