HIP6004DCB-T

Special Purpose Regulators Overview

The HIP6004DCB-T 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 operates from +5V or +12V input and features voltage-mode PWM control with a full 0% to 100% duty ratio. It includes a TTL-compatible 5-bit digital-to-analog output voltage selection with 25mV binary steps ranging from 1.100VDC to 1.850VDC. The controller integrates power-good monitoring, over-voltage protection, and over-current fault detection using the MOSFET's rDS(ON).

Special Purpose Regulators Feature Summary

• Integrates complete control and protection functions for DC-DC converters optimized for microprocessors.
• Features fast transient response via a high-bandwidth error amplifier and simple single-loop voltage-mode design.
• Provides excellent output voltage regulation with ±1% accuracy over line voltage and temperature variations.
• Eliminates the need for extra current sensing elements by utilizing the MOSFET's rDS(ON) for fault monitoring.

Special Purpose Regulators Applications

• Power supply for K7 microprocessors and other similar processors.
• High-power DC-DC regulators.
• Low-voltage distributed power supplies.

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required for automated assembly processes. Confirm the component status as End-of-Life (EOL) through official Renesas notifications prior to procurement planning. Ensure compatibility with existing PCB footprints designed for the QFN package format. Review the latest product change notification (PCN) documents for any updates regarding material composition or manufacturing site changes that may impact long-term supply chain stability.

Special Purpose Regulators Selection Notes

Select this controller when designing synchronous buck converters requiring integrated fault protection without external current sense resistors. The device is suitable for applications demanding precise voltage adjustment via a 5-bit DAC interface. Consider the operating frequency range of 50kHz to over 1MHz for inductor sizing. Verify that the input voltage requirements align with standard +5V or +12V rails available in the system architecture.

Special Purpose Regulators Part Context

The HIP6004 series represents a family of controllers developed for low-voltage, high-current microprocessor power delivery. Originally introduced by Intersil Corporation, the technology was acquired by Renesas Electronics. This specific model focuses on providing a compact solution for processor core voltage regulation, addressing the need for efficient power management in dense electronic designs.

Special Purpose Regulators Replacement Considerations

Public confirmed substitute part numbers are not provided in the available documentation. Due to the End-of-Life status, alternative solutions should be evaluated based on functional equivalence, pin compatibility, and thermal performance characteristics.
