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.
