2A 380KHZ 20V PWM Buck DC/DC Converter TD1410
General Description
The TD1410 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.
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 TD1410 serves as ideal power supply
units for portable devices.
