ISL6269ACRZ

DC DC Switching Controllers Overview

The ISL6269ACRZ is a single-phase synchronous buck PWM controller from Renesas Electronics, utilizing Robust Ripple Regulator (R3) technology. It operates with an input voltage range of 7V to 25V and supports adjustable switching frequencies between 200kHz and 600kHz. The device provides a positive output voltage adjustable from 600mV to 3.3V, capable of delivering up to 25A of output current. Designed for surface mount installation in a 16-VQFN package (4x4 mm), it functions within a temperature range of -10°C to +100°C.

DC DC Switching Controllers Feature Summary

• Implements Robust Ripple Regulator (R3) technology for superior transient response and stability without requiring external compensation components.
• Features integrated synchronous rectification drivers for high efficiency in single-phase buck applications.
• Includes comprehensive control features such as enable, frequency control, phase control, and power good indication.

DC DC Switching Controllers Applications

• High-performance notebook computer CPU core voltage regulation
• Single-phase DC-DC step-down conversion for portable electronics
• GPU or chipset power supply systems requiring fast transient response

DC DC Switching Controllers Procurement Notes

Verify component authenticity through authorized distributors due to potential availability constraints. Confirm RoHS3 compliance and MSL level 3 handling requirements during storage and assembly. Check for specific marking codes to distinguish variants. Ensure ESD protection protocols are followed given the QFN package sensitivity.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring a single-phase solution with minimal external component count. Ideal for designs needing adjustable output voltage and frequency within specified limits. Consider thermal performance and PCB layout constraints associated with the 16-QFN package when integrating into the system.

DC DC Switching Controllers Part Context

Part of the ISL6269 family, which includes variants like the ISL6269CRZ. The series is designed for notebook and mobile computing power management. Renesas acquired Intersil, under which this part was originally developed. The R3 technology differentiates it from traditional PWM controllers by simplifying loop compensation.

DC DC Switching Controllers Replacement Considerations

Direct substitutes may include other single-phase synchronous buck controllers from Renesas or Intersil families. Verify pin compatibility and electrical specifications before substitution. Alternative packages or temperature grades might require design adjustments.
