General Description

The AP2004 integrates Pulse-Width-Modulation

(PWM) control circuit into a single chip, mainly

designs for power-supply regulator. All the functions

include an on-chip 1.25V reference output, an error

amplifier, an adjustable oscillator, a soft-start,

UVLO, SCP circuitry, and a push-pull output circuit.

Switching frequency is adjustable by trimming CT.

During low VCC situation, the UVLO makes sure

that the outputs are off until the internal circuit

operates normally.

Applications

- Backlight inverter

- LCD Monitor

- XDROM, XDSL Product

- DC/DC converters in computers, etc.
