The ISL6752 is a high-performance, low-pin-count alternative zero-voltage switching (ZVS) full-bridge PWM controller. Like Intersil’s ISL6551, it achieves ZVS operation by driving the upper bridge FETs at a fixed 50% duty cycle while the lower bridge FETs are trailing-edge modulated with adjustable resonant switching delays. Compared to the more familiar phase-shifted control method, this algorithm offers equivalent efficiency and improved overcurrent and light-load performance with less complexity in a lower pin count package. This advanced BiCMOS design features precision deadtime and resonant delay control, and an oscillator adjustable to 2MHz operating frequency. Additionally, Multi-Pulse Suppression ensures alternating output pulses at low duty cycles where pulse skipping may occur.
