The MAX5051 is a two-switch power-supply controller IC from Texas Instruments. It can be used in both forward and flyback configurations with an input voltage range of 11V to 76V. It also provides comprehensive protection mechanisms against possible faults, resulting in very high reliability power supplies.
The MAX5051 is a parallelable, clamped two‑switch power‑supply controller IC designed for high‑efficiency isolated power supplies. It supports input voltages from 11 V to 76 V and provides over 2 A of peak gate‑drive current for external MOSFETs. The device includes programmable brown‑out, UVLO, and fault‑protection features, and can operate with secondary‑side synchronous rectification for efficiencies up to 92 %.
The IC is supplied in a 28‑pin TSSOP‑EP package that operates from –40 °C to +125 °C. Detailed electrical characteristics, absolute maximum ratings, and pin configurations are provided, along with typical performance graphs and package drawings.
