ISL6755AAZA

DC DC Switching Controllers Overview

The ISL6755AAZA is a Zero Voltage Switching (ZVS) Full-Bridge PWM controller designed for high-frequency DC-DC conversion. It operates within a supply voltage range of 9V to 16V and supports switching frequencies up to 2 MHz. The device features an operating temperature range from -40°C to +105°C and is housed in a 20-SSOP package with a width of 3.90mm. It implements average current limit protection and includes soft-start functionality.

DC DC Switching Controllers Feature Summary

• Implements Zero Voltage Switching (ZVS) full-bridge topology to minimize switching losses
• Integrates average current limit protection for robust fault management
• Supports high-frequency operation up to 2 MHz for compact magnetics

DC DC Switching Controllers Applications

• High-power density DC-DC converters
• Server and telecom power supplies
• Industrial power systems

DC DC Switching Controllers Procurement Notes

Verify the component status as obsolete or end-of-life through official Renesas notifications before design finalization. Confirm the specific suffix 'AAZA' matches the required 20-SSOP package and anneal specifications. Ensure compatibility with existing PCB footprints and validate thermal performance within the specified -40°C to +105°C operating range.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring ZVS full-bridge topologies with integrated average current limiting. It is suitable for designs needing high switching frequencies up to 2 MHz to reduce passive component size. Consider the 20-SSOP package constraints and the 9V to 16V Vcc requirement when designing the driver circuitry.

DC DC Switching Controllers Part Context

The ISL6755AAZA belongs to the ISL675x series of ZVS full-bridge controllers by Renesas/Intersil. It shares functional similarities with the ISL6753 and ISL6752 but utilizes a 20-SSOP package instead of the 16-QSOP found in those variants. This series targets efficient, high-power isolated DC-DC conversion applications.

DC DC Switching Controllers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements should be evaluated based on pinout compatibility and electrical specifications against newer Renesas full-bridge controllers.
