ISL78223 Datasheet Zvs Full-bridge Pwm Controller

Manufacturer: Intersil (now Renesas)

Overview: ZVS Full-Bridge PWM Controller with Adjustable Synchronous Rectifier Control ISL78223 The ISL78223 is a high-performance zero-voltage switching (ZVS) full-bridge PWM controller. 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. Adding to the ISL78223’s feature set are average current monitoring and soft-start. The average current signal may be used for average current limiting, current sharing circuits and average current mode control. Additionally, the ISL78223 supports both voltage- and current-mode control.

Key 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 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. The ISL78223 is AEC - Q100 rated. The ISL78.
