Information

The ISL6753 is a high-performance, low-pin-countalternative, zero-voltage switching (ZVS) full-bridge PWMcontroller. Like the ISL6551, it achieves ZVS operation bydriving the upper bridge FETs at a fixed 50% duty cycle whilethe lower bridge FETS are trailing-edge modulated withadjustable resonant switching delays. Compared to the morefamiliar phase-shifted control method, this algorithm offersequivalent efficiency and improved overcurrent and lightloadperformance with less complexity in a lower pin countpackage. This advanced BiCMOS design features low operatingcurrent, adjustable oscillator frequency up to 2MHz,adjustable soft-start, internal over temperature protection,precision deadtime and resonant delay control, and shortpropagation delays. Additionally, Multi-Pulse Suppressionensures alternating output pulses at low duty cycles wherepulse skipping may occur.
