The Renesas Zero-Voltage Switching (ZVS) 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.

Adjustable resonant delay for ZVS operation
Synchronous rectifier control outputs with adjustable delay/advance
Current-mode control
Adjustable dead time control
Adjustable oscillator frequency up to 2MHz
Fast current sense to output delay
Pb-free (RoHS compliant)
