AP2008

PWM BUCK CONTROLLER

Features

General Description

• PWM Buck Control Circuitry

• Operating voltage can be up to 20V

• Under voltage Lockout (UVLO) Protection

• Short Circuit Protection (SCP)

• Soft-start circuit

• Variable Oscillator Frequency -- 300Khz Max

• 0.77V voltage reference Output

• 8-pin SOP package

• Lead Free Finish/ RoHS Compliant for Lead Free and

“Green” products (Note 1)

• SOP-8L: Available in “Green” Molding Compound (No

Br, Sb)

The AP2008 integrates Pulse-Width-Modulation (PWM) control

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

regulator. All the functions include an on-chip 0.77V 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 is operational normally.

Applications

• Backlight inverter

• LCD Monitor

• XDROM, XDSL Product

• DC/DC converters in computers, etc.
