AP2008 Description
The AP2008 integrates Pulse-Width-Modulation (PWM) control circuit into a single chip, mainly designs for power-supply regulator. All the functions included an on-chip 0.77V reference output, an error amplifier, an adjusted oscillator, a soft-start, UVLO, SCP circuitry, and a push-pull output circuit. Switching frequency can be adjustable by trimming CT.
