MP103 EasyPower^TM

Higher Power

Offline Inductor-Less Regulator

For Low Power Applications

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP103 provides an easy and low cost

ACDC solution for less than 1W applications. It

is an off-line linear regulator that delivers good

efficiency while generating little EMI noise. It

provides an easy solution to step down the AC

line voltage to a regulated DC voltage. This off-

line linear regulator replaces the conventional

switching regulator, not needing a transformer

or an inductor. Due to its simplicity, it offers an

overall low BOM cost.

•

Universal AC Input (85Vac-305Vac)

Inductor-less

Less than 100mW standby power

Excellent EMI Performance

Lower BOM Cost

Smart Control to Maximizes Efficiency

Adjustable Output Voltage from 1.5V to 15V

Good Line and Load Regulation

Drives External BJT

Short Circuit Protection

External Programmable Over Temperature

Protection (OTP)

MP103 delivers nearly two times the output

power than the MP100 or MP100L by charging

its VB capacitor with an external bipolar

APPLICATIONS

transistor.

MP103 maximizes efficiency by

minimizing the voltage drop between VB and

VOUT, while only charging VB when VIN is less

than approximately 32V. The MP103 enables

the overall system to meet standby power

requirements.

•

Wall switches and dimmers

AC/DC Power Supply for Wireless System,

like ZigBee, Z-Wave

Standby Power for General Off-Line

Applications

•

MP103 offers rich protections, such as Thermal

Shutdown (TSD), Over Temperature Protection

(OTP), VB Over Voltage Protection (OVP), VB

Short to GND Protection, Over Load Protection

(OLP), Short Circuit Protection (SCP), MP103 is

available in the SOIC8E package.

All MPS parts are lead-free and adhere to the RoHS directive. For MPS green

status, please visit MPS website under Products, Quality Assurance page.
