TD3111

2.2A 52KHZ 32V PWM Buck DC/DC Converter

General Description

Features

The TD3111 is a 52 KHz fixed frequency

monolithic step down switch mode regulator

with a built in internal Power MOSFET. It

achieves 2.2A continuous output current over

a wide input supply range with excellent load

and line regulation.

2.2A Constant Output Current

80mΩ R_DSONInternal Power PMOSFET

Switch

Up to 95% Efficiency

Fixed 52KHz Frequency

The device includes a voltage reference,

oscillation circuit, error amplifier, internal

PMOS and etc.

Wide 3.6V to 32V Input Voltage Range

Output Adjustable from 0.8V to 30V

Built in Frequency Compensation

Built in Thermal Shutdown Function

Built in Current Limit Function

SOP-8 Package is Available

The minimum dropout up to 0.3V

The PWM control circuit is able to adjust the

duty ratio linearly from 0 to 100%. An enable

function, an over current protection function

and a short circuit protection function are

built inside. An internal compensation block

is built in to minimize external component

count.

Applications

Portable DVD

LCD Monitor / TV

Battery Charger

The TD3111 serves as ideal power supply

units for portable devices.

ADSL Modem

Telecom / Networking Equipment
