HIP6311CBZ

DC DC Switching Controllers Overview

The HIP6311CBZ is a microprocessor core voltage regulator featuring a multi-phase buck PWM controller. It supports 2, 3, or 4 phase operation with precision channel current sharing using lossless current sampling. The device offers programmable droop voltage and accepts 5-bit VID input for voltages ranging from 1.100V to 1.850V in 25mV steps. It operates within a frequency range of 100kHz to 6MHz, ensuring high ripple frequency relative to the number of channels. The component provides over-current protection and maintains system accuracy of ±0.8% over temperature.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix (e.g., CBZ vs CBZA) against the official Intersil datasheet to confirm package type and RoHS compliance status. Ensure the ordering part number matches the required tape and reel packaging if indicated by a '-T' suffix. Cross-reference the manufacturer's latest documentation to confirm pinout compatibility and thermal specifications before procurement.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring precise multi-phase control for processor cores. Consider the operating frequency range and the need for lossless current sensing when designing the power stage. Verify that the 5-bit VID interface aligns with the target processor's voltage identification requirements. Ensure the SOIC package fits the available PCB footprint and thermal management strategy.

DC DC Switching Controllers Part Context

The HIP6311 series belongs to Intersil's family of microprocessor core voltage regulators. These controllers are designed to drive multiple MOSFETs in a buck topology. The CBZ variant denotes a Pb-free, RoHS-compliant version in a 20-lead SOIC package. Intersil has been acquired by Renesas Electronics Corporation, which continues to support these legacy components.

DC DC Switching Controllers Replacement Considerations

Check for HIP6311CB or HIP6311CBZA as potential variants with identical functionality but different packaging or material compositions. Verify pin-to-pin compatibility with any alternative multi-phase buck controllers from other manufacturers.
