YB1682
2A 380KHz 20V PWM Buck DC/DC Converter
Description
The YB1682 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
YB1682 serves as ideal power supply units
for portable devices.
