MIC28500 Datasheet - Micrel Semiconductor

MIC28500 Synchronous DC-DC Buck Regulator

The Micrel MIC28500 is an adjustable frequency, synchronous buck regulator featuring a unique adaptive ontime control architecture. The MIC28500 operates over an input supply range of 30V to 75V and provides a regulated output of up to 4A of output current. The output voltage is adjustable down to 0.

MIC28500 Features

* to ensure protection of the IC during fault conditions. These include undervoltage lockout to ensure proper operation under power-sag conditions, internal soft-start to reduce inrush current, foldback current limit, “hiccup” mode shortcircuit protection and thermal shutdown.
