General Description

Features

The TD7580 is a 240 KHz fixed frequency

monolithic step down switch mode regulator

with a built in internal Power MOSFET. It

achieves 4A continuous output current over a

wide input supply range with excellent load

and line regulation.

4A Constant Output Current

80mΩ R_DSONInternal Power PMOSFET

Switch

Up to 95% Efficiency

Fixed 240KHz Frequency

Wide 3.6V to 23V Input Voltage Range

Output Adjustable from 1.222V to 21V

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 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.

Applications

Portable DVD

LCD Monitor / TV

Battery Charger

ADSL Modem

The TD7580 serves as ideal power supply

units for portable devices.
