Preliminary Product Information

2-Channel PWM Controller for CCFL Backlight

Features

General Description

• High-accuracy reference voltage circuit (±2%). The AT1741 is 2-channel PWM switching

• Built-in short-circuit protection circuit.

• Built-in Undervoltage Lockout protection.

• Internal 2.5V Reference supply.

• Variable Dead time provides control over total

Range.

regulator controllers that contains an on-chip 2.5V

reference, two error amplifier, an adjustable

oscillator, two dead-time comparators, under-

voltage lockout circuitry and 2 common-emitter

output. It is idea for step-up, step-down, and

inverting converter.

Applications

• LCD CCFL Backlight

• Portable equipment
