DC DC Switching Controllers datasheet and documents for ISL6431CB

ISL6431CB

DC DC Switching Controllers Overview

The ISL6431CB is a PWM controller designed for step-down DC-DC switching applications. It operates with a fixed switching frequency of 300kHz and supports a minimum output voltage of 0.8V with a tolerance of ±1.5%. The device accepts a +5V input supply and features resistor-programmable settings. It includes synchronous rectification capabilities and phase control features, operating within a temperature range of 0°C to 70°C.

DC DC Switching Controllers Feature Summary

Supports synchronous rectification for improved efficiency in step-down configurations.
Features phase control functionality for precise regulation.
Utilizes resistor programming for flexible configuration options.

DC DC Switching Controllers Applications

Step-down DC-DC power supply designs
Systems requiring 0.8V minimum output voltage regulation
Industrial equipment with +5V input constraints

DC DC Switching Controllers Procurement Notes

Verify component authenticity as the ISL6431CB is listed as obsolete by the manufacturer. Confirm RoHS compliance status, as specific suffixes may indicate non-compliance. Ensure the package type matches system requirements before procurement. Check for available substitutes if new production units are unavailable.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring a 300kHz switching frequency and synchronous rectification. It is suitable for designs needing a 0.8V minimum output with tight tolerance. Consider the +5V input requirement and limited operating temperature range when evaluating suitability for the target environment.

DC DC Switching Controllers Part Context

The ISL6431CB belongs to the Intersil (now Renesas) family of PMIC switching controllers. It is categorized under DC-DC switching controllers with a step-down function. The device is part of a series that includes variants like the ISL6431ACB, sharing similar core functionalities but potentially differing in packaging or specific electrical characteristics.

DC DC Switching Controllers Replacement Considerations

Public confirmed substitute part numbers are not explicitly documented in the provided source material. Users should consult official Renesas documentation for cross-reference recommendations due to the obsolete status of this specific model.
