EC9410
2A 380KHZ 20V PWM Buck DC/DC Converter
General Description
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.
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
c ircu i t protection function are built inside. An
internal compensation block is built in to minimize
external component count.
The EC9410 serves as ideal power supply units
for portable devices.
