ISL6752AAZA-T

DC DC Switching Controllers Overview

The ISL6752AAZA-T is a high-performance, low-pin-count Zero Voltage Switching (ZVS) Full Bridge PWM controller manufactured by Renesas Electronics. It operates at switching frequencies up to 2 MHz with a maximum duty cycle of 99%. The device supports a supply voltage range of 9 V to 16 V and provides one output channel configured for boost/buck DC-DC conversion. It features synchronous rectifier control and is housed in a 16-QSOP package.

DC DC Switching Controllers Feature Summary

• Implements ZVS operation via fixed 50% duty cycle drive for upper bridge FETs and rear-edge modulation for lower bridge FETs.
• Provides complementary PWM outputs for synchronous rectifier control with dynamic phase adjustment capabilities.
• Integrates adjustable peak current limit, leading edge blanking, and multi-pulse suppression for robust performance.

DC DC Switching Controllers Applications

• ZVS full bridge converters
• Telecommunications and data communication power supplies
• Wireless base station power systems

DC DC Switching Controllers Procurement Notes

Verify component status as the manufacturer has issued discontinuation notifications indicating end-of-life status. Confirm availability through authorized distributors or secondary market channels. Ensure compliance with RoHS3 specifications and check moisture sensitivity level requirements prior to handling and soldering processes.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring high efficiency in full bridge topologies without complex phase-shift algorithms. It serves as a pin-compatible alternative to legacy controllers like the ISL6551. Consider thermal management due to the operating temperature range of -40°C to +105°C and verify compatibility with external gate drive circuits for optimal switching performance.

DC DC Switching Controllers Part Context

This component belongs to the ISL6752 series of power management ICs designed for advanced AC/DC and DC/DC conversion applications. It utilizes BiCMOS technology to deliver precise dead-time and resonant delay control. The product line targets high-density power supplies where reduced pin count and improved light-load performance are critical design constraints.

DC DC Switching Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, direct replacements may require redesigning the application circuit to accommodate differences in pinout, control algorithm, or electrical characteristics.
