EC9410

2A 380KHZ 20V PWM Buck DC/DC Converter

Features

General Description

2A Constant Output Current

140m Internal Power PMOSFET

Switch

The EC9410 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.

Ω

DSON

Up to 95% Efficiency

Fixed 380KHz Frequency

Wide 3.6V to 20V Input Voltage Range

Output Adjustable from 1.222V to 18V

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.

SOP8 Package is Available

The minimum dropout up to 0.3V

Applications

Portable DVD

LCD Monitor / TV

Battery Charger

The EC9410 serves as ideal power supply units

for portable devices.

ADSL Modem

Telecom / Networking Equipment
