ISL6752AAZA - Renesas Electronics
Description: The ISL6752 is a high-performance, low-pin count alternative Zero-Voltage Switching (ZVS) full-bridge PWM controller. Like Renesas' 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
