Preliminary

2-Channel PWM Controller for LCD Bias

Features

General Description

• Low input voltage: 2.5V to 7V

• 2-Channels PWM Control:

1 Boost Controller(CH1)

The AT1731 is a PWM DC/DC converter control

IC with 2 channel outputs that can directly drive

power MOSFET. This IC ia suitable for very small

DC/DC converters because of their small and thin

package(1.1 mm max.), and high operation

frequency (up to 1.0 MHz).

1 Inverting Controller (CH2)

• Adjustable Soft start time and maximum duty

cycle

• Built-in timer latch for short circuit protection:

Delay time=2 /(Switching frequency)

• Built-in under-voltage lockout, thermal

shutdown.

• High operating frequency: 100kHz to 1MHz

Applications

• LCD Displays Bias

• Power Supply for general equipment
