General Description

The TD1410C is a 380 KHz fixed frequency

monolithic step down switch mode regulator

with a built in internal Power MOSFET. It

achieves 1.8A continuous output current over

a wide input supply range with excellent load

and line regulation.

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.

The TD1410C serves as ideal power supply

units for portable devices.
