DESCRIPTION

The MP100 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 MP100 provides various protections, such

as

over-current

protection,

short-circuit

protection, VD over-voltage protection, VD

under-voltage lockout, and thermal shutdown.

The MP100 is available in a SOIC8E package.

FEATURES

• Universal AC Input (85VAC-to-305VAC)

• Smart Control to Maximize Efficiency

• Adjustable Output Voltage from 1.5V to 15V

• Low Component Count and Cost

• Thermal Shutdown Protection

• Short-Circuit Protection

• Provide Power-Good Signal

• No Bulk Capacitor Required

APPLICATIONS

• Wall Switches and Dimmers

• AC/DC Power Supply for Wireless System,

like ZigBee,Z-Wave and so on

• Standby Power for General Off-Line

Applications
