Description
The MAX5075 is a +4.5V to +15V push-pull, current-fed topology driver subsystem with an integrated oscillator for use 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. This device features a programmable, accurate, integrated oscillator with a synchronizing clock output that synchronizes an external PWM regulator. A single external resistor programs the internal oscillator frequency from 50kHz to 1.5MHz.

The MAX5075 incorporates a dual MOSFET driver with ±3A peak drive currents and 50% duty cycle. The MOSFET driver generates complementary signals to drive external ground-referenced n-channel MOSFETs.

The MAX5075 is available with a clock output frequency to MOSFET driver frequency ratio of 1x, 2x, and 4x. The MAX5075 is available in a thermally enhanced 8-pin µMAX® package and is specified over the -40°C to +125°C operating temperature range.
