About This Product

■Summary

The MP103 provides a simple, low-cost AC/DC solution for sub-1W applications. This is an offline linear regulator that generates almost no EMI noise and achieves excellent efficiency. Provides an easy solution to step down AC line voltage to a regulated DC voltage. This offline linear regulator replaces traditional switching regulators and requires no transformers or inductors. Due to its simplicity, BOM costs are lower overall. The MP103 provides nearly twice the output power compared to the MP100 or MP100L by charging the VB capacitor with an external bipolar transistor. The MP103 maximizes efficiency by minimizing the voltage drop between VB and VOUT while charging VB only when VIN is less than approximately 32V. MP103 allows the entire system to meet standby power requirements. MP103 provides rich protection such as thermal shutdown (TSD), overtemperature protection (OTP), overvoltage protection (OVP) on VB, short circuit protection between VB and GND, overload protection (OLP), and short circuit protection (SCP). MP103 is offered in SOIC8E package.

■Features and benefits

・Universal AC input (85Vac-305Vac) ・Inductorless ・Standby power less than 100mW ・Excellent EMI performance ・Reduction of BOM cost ・Smart control to maximize efficiency ・Adjustable output voltage from 1.5V to 15V ・Good line and load regulation ・Drive external BJT ・Short circuit protection ・Externally programmable overtemperature protection ・Protection (OTP)

■Available product numbers

・MP103GN-P MP103GN-Z MP103GN ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
