HIP6004DCB

Special Purpose Regulators Overview

The HIP6004DCB is a Buck and Synchronous-Rectifier PWM Controller and Output Voltage Monitor manufactured by Renesas Electronics Corporation. Designed for high-performance microprocessor applications, it drives two N-channel MOSFETs in a synchronous-rectified buck topology. The device integrates control, output adjustment, monitoring, and protection functions. It operates from +5V or +12V inputs and features voltage-mode PWM control with a full 0% to 100% duty ratio. Key electrical parameters include an output voltage range of 1.100VDC to 1.850VDC with 25mV binary steps via a TTL-compatible 5-bit digital-to-analog converter. The oscillator frequency is programmable from 50kHz to over 1MHz.

Special Purpose Regulators Feature Summary

• Integrates complete control and protection for DC-DC converters optimized for microprocessors
• Utilizes simple single-loop voltage-mode PWM control design
• Employs MOSFET rDS(ON) for over-voltage and over-current fault monitoring without extra sensing elements
• Features fast transient response through a high-bandwidth error amplifier

Special Purpose Regulators Applications

• Power supply for K7 microprocessors
• High-power DC-DC regulators
• Low-voltage distributed power supplies

Special Purpose Regulators Procurement Notes

Verify the manufacturer designation carefully, as the component was originally developed by Intersil Corporation before its acquisition by Renesas. Confirm that the specific suffix 'DCB' corresponds to the Quad Flat No Leads (QFN) package variant described in official datasheets. Ensure compliance with current RoHS standards and check for any Product Change Notifications (PCN) regarding labeling or material updates. Validate that the source documentation explicitly supports the part number and package type to avoid substitution errors.

Special Purpose Regulators Selection Notes

Select this controller when designing synchronous buck converters for low-voltage microprocessor power delivery. It is suitable for applications requiring precise output voltage regulation within the 1.1V to 1.85V range. The integration of fault monitoring using existing MOSFET characteristics simplifies the bill of materials. Consider the QFN package footprint if PCB space efficiency and thin profile are critical design constraints.

Special Purpose Regulators Part Context

The HIP6004 series belongs to a family of specialized power management integrated circuits designed for CPU core voltage regulation. Originally introduced by Intersil, these controllers were widely adopted in early 2000s computing platforms. The HIP6004DCB specifically targets the QFN form factor, offering a near chip-scale package footprint that improves PCB efficiency compared to larger leaded packages like SOIC or DIP variants found in other series members.

Special Purpose Regulators Replacement Considerations

Publicly confirmed substitute part numbers for the specific HIP6004DCB variant are not available in the provided reference data. Users should consult official Renesas replacement guides or distributor cross-reference tools for compatible alternatives.
