products (Note 1)

The AP2001 integrates Pulse-width-Modulation (PWM) control

circuit into a single chip, mainly designed for power-supply

regulator. All the functions included are an on-chip 2.5V

reference output, two error amplifiers, an adjustable oscillator,

two dead-time comparators, UVLO, SCP, DTC circuitry, and dual

common-emitter (CE) output transistor circuit.

Recommend the output CE transistors as pre-driver for Driving

externally. The DTC can provide from 0% to 100%. Switching

frequency can be adjustable by trimming RT and CT. During low

the internal circuit is operating normally.

•

Backlight inverter

•

DC/DC converts in computers, etc.
