2A 380KHz 23V PWM Buck DC/DC Converter

TD1538

General Description

Features

The TD1538 is a 380 KHz fixed frequency monolithic

step down switch mode regulator with a built in internal

Power MOSFET. It achieves 2A continuous output

current over a wide input supply range with excellent

load and line regulation.

2A Constant Output Current

140mΩ R_DSONInternal Power PMOSFET Switch

Up to 95% Efficiency

Fixed 380KHz Frequency

Wide 1.0V to 23V Input Voltage Range

Output Adjustable from 0.8V to 21V

Built in Frequency Compensation

Built in Thermal Shutdown Function

Built in Current Limit Function

The device includes a voltage reference, oscillation

circuit, error amplifier, internal PMOS and etc.

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.

SOP-8 Package is Available

The minimum dropout up to 0.3V

The TD1538 serves as ideal power supply units for

portable devices.

Applications

Portable DVD

LCD Monitor / TV

Battery Charger

ADSL Modem

Telecom / Networking Equipment
