Overview

LM25184 is a primary-side regulation (PSR) flyback converter with high efficiency over a wide input voltage range of 4.5V to 42V, sampling the isolated output voltage via the primary-side flyback voltage. High integration enables simple, reliable, high-density designs with only a single component crossing the isolation barrier. Boundary conduction mode (BCM) switching enables a compact magnetics solution and load and line regulation performance better than ±1.5%. An integrated 65V power MOSFET delivers up to 15W of output power and increases margin against line transients. The LM25184 simplifies the implementation of isolated DC/DC power supplies, with optional features to optimize performance for target end equipment. The device sets the output voltage with a single resistor, while an optional resistor improves output voltage accuracy by compensating for the temperature coefficient of the flyback diode forward voltage drop. Additional features include internal fixed or externally programmable soft-start, a precision enable input with hysteresis for adjustable line UVLO, hiccup-mode overload protection, and thermal shutdown with automatic recovery.
