ISL6569CB-T

DC DC Switching Controllers Overview

The ISL6569CB-T is a multi-phase PWM controller designed for core-voltage regulation. It drives two interleaved synchronous-rectified buck-converter channels in parallel to support high current loads up to 60 A. The device operates with an input voltage range of 4.75 V to 5.25 V and features a switching frequency adjustable from 25 kHz to 1 MHz. Output voltage regulation is maintained between 800 mV and 1.55 V with a maximum duty cycle of 75%. It functions within an operating temperature range of 0°C to +70°C and is housed in a 24-SOIC package.

DC DC Switching Controllers Feature Summary

• Dual-channel interleaved control architecture for enhanced thermal distribution and ripple cancellation

DC DC Switching Controllers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm lot traceability and humidity sensitivity handling requirements upon receipt. Ensure storage conditions comply with JESD22-A113 standards to prevent moisture-induced damage during reflow soldering processes.

DC DC Switching Controllers Selection Notes

Select this component when dual-phase interleaved control is required for moderate current applications up to 60 A. Consider the 24-SOIC package constraints for PCB layout space. Evaluate the fixed input voltage range suitability against system supply rails. Compare thermal performance requirements against the specified operating temperature limits before integration into final designs.

DC DC Switching Controllers Part Context

The ISL6569 series belongs to Intersil's portfolio of multi-phase PWM controllers, now under Renesas Electronics. This specific model represents an earlier generation solution for synchronous buck conversion. It serves as a foundational component for systems requiring simplified power stage design while maintaining stable output voltages for sensitive digital logic circuits.

DC DC Switching Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in verified documentation. Due to the obsolete product status, alternative components must be selected based on functional equivalence including pin compatibility, electrical specifications, and thermal characteristics without guaranteed drop-in replacement.
