Part Details:

19-3663; Rev 1; 6/07 Push-Pull FET Driver with Integrated Oscillator and Programmable Clock Output MAX5077 General Description Features The MAX5077 is a +4.5V to +15V push-pull, current-fed Dedicated Current-Fed, Push-Pull Driver topology driver subsystem with an integrated oscillator Subsystem used in telecom module power supplies. The devicedrives two MOSFETs connected to a center-tapped Oscillator Frequency Programmable from 50kHz transformer primary providing secondary-side, isolated, to 1.5MHz negative or positive voltages. The MAX5077 features a Single +4.5V to +15V Supply Voltage Range programmable accurate integrated oscillator with asynchronizing clock output to synchronize an external ±3A Peak Gate-Drive Current PWM regulator. A single external resistor programs the 1mA Operating Current at 250kHz with No internal oscillator frequency from 50kHz to 1.5MHz. Capacitive Load The MAX5077 incorporates dual MOSFET drivers with±3A peak drive currents and 50% duty cycle. The Selectable Synchronizing Clock Frequency for a MOSFET drivers generate complementary signals to Preceding PWM Stage drive external ground-referenced n-channel MOSFETs. Thermally Enhanced 14-Pin TSSOP The MAX5077 clock output frequency is programmable -40°C to +125°C Operating Temperature Range by logic inputs to set the clock output to 1x, 2x, or 4xthe MOSFET s driver frequency. The MAX5077 is available in a 14-pin exposed padTSSOP package and is specified over the -40°C to Ordering Information +125°C operating temperature range.
