Product details
Overview
HIP6004DCRZ-T from Intersil is a synchronous-rectified buck PWM controller with integrated voltage-mode regulation, 5-bit VID DAC, and MOSFET rDS(ON)-based overcurrent sensing. It delivers precise 1.10–1.85V output (±1% regulation), supports 50kHz–1MHz programmable switching frequency, and drives two N-channel MOSFETs for microprocessor core power supplies.
For engineers reviewing the HIP6004DCRZ-T datasheet, HIP6004DCRZ-T pinout, HIP6004DCRZ-T application, or HIP6004DCRZ-T equivalent, key selection criteria include its 20-pin QFN package, TTL-compatible VID interface, 15MHz error amplifier GBWP, ±10% PGOOD window, and absence of external current-sense resistors.
Technical Context
The HIP6004DCRZ-T implements voltage-mode PWM control using a 200kHz free-running oscillator adjustable via RT-to-GND or RT-to-VCC resistor networks. Its error amplifier provides 15MHz gain-bandwidth and 6V/µs slew rate to support fast transient response in high-current CPU VRMs.
Overcurrent protection uses an internal 200µA current source at OCSET to sense upper-MOSFET rDS(ON), eliminating discrete sense resistors. Power-good monitoring tracks DACOUT with ±10% window and 2% hysteresis, while OVP triggers external SCR crowbar at +115% DACOUT.

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck PWM controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL6260CRZ-T | Higher integration: includes MOSFET drivers, OVP, and thermal shutdown; supports 3-phase operation | Targeted at multi-phase CPU VRMs; not drop-in compatible due to different pinout and feature set | Choose ISL6260CRZ-T only for new multi-phase designs requiring higher current capacity and advanced telemetry |
| HIP6301CBZ-T | Legacy SOIC-20 package; identical functional spec but lacks QFN thermal performance and RoHS compliance | Same VID range and control architecture, but limited to lower-power applications due to higher θJA (65°C/W) | Select HIP6301CBZ-T only for legacy board rework where QFN reflow is unavailable or thermal budget permits |
Compared with HIP6004DCRZ-T, ISL6260CRZ-T adds multi-phase coordination and telemetry at the cost of pin compatibility and design simplicity, while HIP6301CBZ-T retains identical functionality in a thermally inferior SOIC package - making HIP6004DCRZ-T optimal for new single-phase, space-constrained, RoHS-compliant designs.

FAQ
What is the maximum switching frequency supported by the HIP6004DCRZ-T?
The HIP6004DCRZ-T supports a switching frequency range from 50kHz to over 1MHz, programmable via an external resistor connected to the RT pin. With RT tied to ground, the typical free-running frequency is 200kHz; increasing RT resistance raises frequency, while pulling RT to VCC lowers it per datasheet equations. This flexibility allows optimization for efficiency, size, or EMI requirements in the final design.
Does the HIP6004DCRZ-T require an external current-sense resistor?
No, the HIP6004DCRZ-T does not require an external current-sense resistor. It implements overcurrent protection by monitoring the voltage drop across the upper MOSFET's rDS(ON) using the OCSET pin and an internal 200µA current source. This eliminates BOM cost and PCB area associated with discrete sense resistors while maintaining accurate current limiting in the HIP6004DCRZ-T-based converter.
How is the output voltage programmed on the HIP6004DCRZ-T?
The HIP6004DCRZ-T uses a 5-bit TTL-compatible digital-to-analog converter (DAC) with VID0–VID4 pins to program the output voltage in 25mV increments from 1.100V to 1.850V. Each VID pin state (0 = grounded, 1 = pulled high) selects one of 32 discrete DACOUT reference voltages, which directly sets the regulated output, PGOOD thresholds, and OVP trip points - all without external components.
What is the purpose of the separate GND and PGND pins on the HIP6004DCRZ-T?
The HIP6004DCRZ-T separates signal ground (GND, Pin 11) from power ground (PGND, Pin 16) to isolate noise-sensitive analog circuitry - including the error amplifier, DAC, and comparators - from high-current switching paths. This separation minimizes ground bounce and improves regulation accuracy and stability in the HIP6004DCRZ-T-controlled buck converter, especially under fast load transients.
Can the HIP6004DCRZ-T be used with a +5V input supply instead of +12V?
Yes, the HIP6004DCRZ-T operates from either +5V or +12V input on the VCC pin, as specified in the Absolute Maximum Ratings and Recommended Operating Conditions. While +12V is typical for higher-power microprocessor VRMs, the +5V option supports lower-power applications or systems with existing 5V bias rails - with no change to the HIP6004DCRZ-T's functionality or pin configuration.
