Offline Inductor-Less Regulator

For Low Power Application

DESCRIPTION

The MP100L is a compact, inductor-less, good-

efficiency, off-line regulator. It steps down the

AC line voltage to an adjustable DC output. It is

a simple solution to provide a bias voltage to

ICs in off-line applications. Its integrated smart-

control system uses AC line power only when

necessary, thus minimizing device losses to

achieve good efficiency. This device can help

system designs meet new standby power

specifications.

The MP100L provides various protections, such

as Thermal Shutdown (TSD), VD Over Voltage

Protection (OVP), VD Shrot to GND Protection,

Over Load Protection (OLP), Short Circuit

Protection (SCP).

The MP100L is available in SOIC8E package.
