General 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 pro-
grammable, accurate, integrated oscillator with a syn-
chronizing 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.
