ISL78223 - ZVS Full-Bridge PWM Controller

Description

The 5V reference voltage output with 3% tolerance over line, load, and operating temperature.

Bypass to GND with a 0.1µF to 2.2µF low ESR capacitor.

Features

  • complemented PWM outputs for Synchronous Rectifier (SR) control. The complemented outputs can 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 rated for the automotive tem.

DATASHEET ISL78223 ZVS Full-Bridge PWM Controller with Adjustable Synchronous Rectifier Control FN7936 Rev.4.00 May 8, 2017 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 can be used for average current limiting, current sharing circuits, and average current mode control. Additionally, the ISL78223 supports both voltage and current mode control. The ISL78223 features complemented PWM outputs for Synchronous Rectifier (SR) control.
