The AP2002 is a low-cost, full-featured, synchronous voltage-mode controller designed for use with single-ended power supply applications where efficiency is the primary concern. This synchronized operation can eliminate heat sinks in many applications. The AP2002 is ideal for implementing DC/DC converters that require low cost systems in advanced microprocessor power supply applications where distributed power efficiency is very important. Internal level shifting, high-side driver circuitry, and preset beat-through controls allow the use of inexpensive N-channel power switches. AP2002 features include temperature compensated reference voltage, internal 200kHz virtual high frequency oscillator, under voltage lockout protection, soft start function and current sense comparator circuit. Power good signal, shutdown, over voltage protection is provided for AP2002.
