ISL6752AAZA-T Common Ic Chips Regulator Output Controller IC 16-QSOP

ISL6752AAZA-T Full-Bridge Regulator Positive Isolation Capable Output Controller IC 16-QSOP

The 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 delay/advance

• Current-mode control

• 3% current limit threshold

• Adjustable dead time control

• 175µA start-up current

• Supply UVLO

• Adjustable oscillator frequency up to 2MHz

• Internal over-temperature protection

• Buffered oscillator sawtooth output

• Fast current sense to output delay

• Adjustable cycle-by-cycle peak current limit

• 70ns leading edge blanking

• Multi-pulse suppression

• Pb-free (RoHS compliant)

Applications

• ZVS full-bridge converters

• Telecom and datacom power

• Wireless base station power

• File server power

• Industrial power systems
