2 Channel Linear Controller with Enable Function

Features

General Description

- 2 Channel Linear Control Circuitries

- Operating voltage can be up to 20V

- Under voltage Lockout (UVLO) Protection

- Current Limit

The AP450 series integrates two channel linear

controllers into a single chip, mainly designs for

power-supply regulator. All the functions included

an on-chip 1.25V/0.8V reference output, error

amplifier, UVLO, current limit. During low VCC

situation, the UVLO makes sure that the outputs

are off until the internal circuit is operational

normally.

- Over Voltage Protection

- Power Good Function

- 1.25V/0.8V internal voltage reference

- 8-pin PDIP and SOP Pb-Free packages

Applications

- Backlight inverter

- LCD Monitor

- XDROM, XDSL Product
