YB1685
2A 380KHz 32V PWM Buck DC/DC Converter
Description
The YB1685 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 YB1685 serves as ideal power supply
units for portable devices.
