MAX5077 - Push-Pull FET Driver

Description

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.

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 cycle. The MOSFET drivers generate complementary signals to drive external ground-referenced n-channel MOSFETs. The MAX5077 clock output frequency is programmable by logic inputs to set the clock out.
