ISL8107IRZ

DC DC Switching Controllers Overview

The ISL8107IRZ is a single-phase, non-synchronous buck PWM controller manufactured by Renesas Electronics Corporation. It operates within an input voltage range of 9V to 75V and supports switching frequencies from 100kHz to 600kHz. The device features an integrated high-side MOSFET driver with a maximum output current of 20mA and a fixed output voltage of 10V. Designed for industrial applications, it functions reliably across a temperature range of -40°C to +85°C. The component is housed in a 16-VQFN (5x5mm) package with an exposed pad for thermal management.

DC DC Switching Controllers Feature Summary

• Integrates a high-side MOSFET driver for external N-channel switch control
• Includes input voltage feed-forward compensation for improved line regulation
• Provides overcurrent protection mechanisms for system safety
• Supports clock synchronization for multi-phase or noise-sensitive designs

DC DC Switching Controllers Applications

• Industrial power supply systems
• Telecommunications infrastructure equipment
• Automotive electronics requiring wide input voltage ranges
• General-purpose DC-DC conversion modules

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'IRZ' against the manufacturer's datasheet to confirm the RoHS-compliant lead-free status and tape-and-reel or tube packaging details. Confirm that the component status remains End-of-Life (EOL) as indicated by public notices. Ensure compatibility with existing PCB footprints for the 16-QFN package before finalizing procurement plans due to potential supply chain constraints.

DC DC Switching Controllers Selection Notes

Select this controller when a wide input voltage range up to 75V is required for non-synchronous buck applications. It is suitable for designs needing integrated high-side drive without external gate drivers. Consider the 100kHz to 600kHz frequency range for balancing efficiency and component size. Verify that the external MOSFET selection aligns with the driver's 20mA output capability and the 10V drive voltage specification.

DC DC Switching Controllers Part Context

The ISL8107 belongs to the ISL8107 series of single-phase PWM controllers. This series focuses on robust performance in industrial environments with wide input voltage capabilities. The part integrates essential control features into a compact QFN package, reducing external component count compared to discrete solutions.

DC DC Switching Controllers Replacement Considerations

Public documentation indicates no recommended replacements are available for this end-of-life part. Engineers must evaluate alternative components based on pinout compatibility, electrical specifications, and package dimensions. Cross-reference with current Renesas portfolios for similar wide-input buck controllers.
