The AP2007 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 AP2007 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. High-side drive circuitry, and preset shoot-thru control, allows the use of inexpensive 1P+1N-channel power switches.
The Anachip AP2007 is a low-cost, full-featured synchronous voltage-mode controller designed for single-ended power supply applications where efficiency is of primary concern. It utilizes Virtual Frequency Control™ technology to provide stable constant frequency operation with fast transient response while minimizing external component count.
Key features include a 4.5V to 20V supply range, an internal 200kHz oscillator, soft-start and shutdown functions, under-voltage lockout protection, and short circuit protection. The device is ideal for implementing DC/DC converters to power microprocessors in low-cost systems or distributed power applications.
| Supply Voltage Range | 4.5V to 20V |
|---|---|
| Reference Voltage | 0.8V + 2.0% |
| Oscillator Frequency | 200 KHz |
| Operating Temperature Range | -40 to +85 °C |
