Description:

Current-Mode PWM Buck Controller

Features

* foldback current limiting that greatly reduces input current and component power dissipation during output overload or short-circuit conditions. The compensation and shutdown control (COMP) input, in addition to providing compensation to the error amplifier, can be pulled low to shut down the conver

Applications

* where cost and size are critical. The MAX1954A operates from an input voltage range of 3.0V to 13.2V, independent of the IC supply. The output voltage is adjustable down to 0.8V. The IC operates at a fixed 300kHz switching frequency and provides up to 25A of output current with efficiency up to 95%.
