ISL6752AAZA-T Full-Bridge Regulator Positive Isolation Capable
Output Controller IC 16-QSOPThe 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.The ISL6752 features complemented PWM outputs for Synchronous
Rectifier (SR) control. The complemented outputs may be dynamically
advanced or delayed relative to the PWM outputs using an external
control voltage.This advanced BiCMOS design features precision dead time 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. Features• Adjustable resonant delay for ZVS operation• Synchronous rectifier control outputs with adjustable
