MAX5077 Push-Pull FET Driver

The MAX5077 is a +4.5V to +15V push-pull, current-fed topology driver subsystem with an integrated oscillator used in telecom module power supplies. The device drives two MOSFETs connected to a center-tapped transformer primary providing secondary-side, isolated, negative or positive voltages. The M.

MAX5077 Features

* a programmable accurate integrated oscillator with a synchronizing clock output to synchronize an external PWM regulator. A single external resistor programs the internal oscillator frequency from 50kHz to 1.5MHz. The MAX5077 incorporates dual MOSFET drivers with ±3A peak drive currents and 50% duty
