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.

• Backlight inverter

• LCD Monitor

• CDROM, XDSL Product

• DC/DC converters in computers, etc.
