TM MP103 EasyPower 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 Universal AC Input (85Vac-305Vac) ACDC solution for less than 1W applications. It Inductor-less is an off-line linear regulator that delivers good Less than 100mW standby power efficiency while generating little EMI noise. It Excellent EMI Performance provides an easy solution to step down the AC Lower BOM Cost line voltage to a regulated DC voltage. This off- Smart Control to Maximizes Efficiency line linear regulator replaces the conventional Adjustable Output Voltage from 1.5V to 15V switching regulator, not needing a transformer Good Line and Load Regulation or an inductor. Due to its simplicity, it offers an Drives External BJT overall low BOM cost. Short Circuit Protection MP103 delivers nearly two times the output External Programmable Over Temperature power than the MP100 or MP100L by charging Protection (OTP) its VB capacitor with an external bipolar APPLICATIONS transistor. MP103 maximizes efficiency by minimizing the voltage drop between VB and Wall switches and dimmers VOUT, while only charging VB when VIN is less AC/DC Power Supply for Wireless System, than approximately 32V. The MP103 enables like ZigBee, Z-Wave the overall system to meet standby power Standby Power for General Off-Line requirements. Applications MP103 offers rich protections, such as Thermal All MPS parts are lead-free and adhere to the RoHS directive.
