Product details
Overview
HIP6004DCR-T from Intersil is a synchronous-rectified buck PWM controller with integrated voltage-mode regulation, 5-bit VID DAC, and MOSFET rDS(ON)-based current 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 HIP6004DCR-T datasheet, HIP6004DCR-T pinout, HIP6004DCR-T application, or HIP6004DCR-T equivalent, key selection criteria include its 20-pin 5×5 mm QFN package, TTL-compatible VID interface, 15 MHz error amplifier GBWP, OVP/OC protection architecture, and absence of external current-sense resistors.
Technical Context
The HIP6004DCR-T implements voltage-mode PWM control using a 200 kHz free-running oscillator adjustable via RT-to-GND or RT-to-VCC resistor networks. Its error amplifier provides 15 MHz gain-bandwidth and 6 V/µs slew rate to support fast transient response in high-current CPU VRMs.
Overcurrent protection uses an internal 200 µA 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 action at 115–120% DACOUT.

| VCC (18) | Bias supply input | Accepts +12 V ±10% - powers internal circuitry and gate drivers; requires local 10 µF decoupling |
| OVP (19) | Overvoltage crowbar trigger | Open-drain output asserts high at 115–120% DACOUT - drives external SCR to short input rail on fault |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL6522CRZ | Same 20-pin QFN package; includes integrated MOSFET drivers but lacks VID DAC and uses current-mode control | Requires external DAC or resistor ladder for voltage setting; better suited for fixed-output or analog-programmed systems | Select ISL6522CRZ when current-mode control and higher integration (e.g., bootstrap diode) are prioritized over VID compatibility |
| TPS51116PWR | Supports 1.5–3.3 V range with 6-bit VID; adds 5 V LDO and thermal shutdown but uses 24-pin TSSOP package | Broader voltage range and additional power management features; not drop-in compatible due to pin count and layout | Choose TPS51116PWR for newer platforms needing wider VID range and integrated auxiliary power, accepting PCB redesign |
Compared with ISL6522CRZ and TPS51116PWR, the HIP6004DCR-T offers unique combination of VID-based voltage selection, rDS(ON) current sensing, and QFN thermal performance - making it optimal for legacy K7™-class CPU power where pin compatibility and minimal BOM are critical.

FAQ
What is the operating temperature range for the HIP6004DCR-T?
The HIP6004DCR-T is specified for operation from 0°C to +70°C ambient temperature. This commercial-grade range aligns with its target use in desktop and embedded computing applications where airflow and thermal design ensure junction temperatures remain below the absolute maximum of 150°C. The QFN package's θJA of 33°C/W supports this rating under standard PCB mounting conditions.
Does the HIP6004DCR-T require an external current-sense resistor?
No, the HIP6004DCR-T does not require an external current-sense resistor. It implements overcurrent protection by measuring the voltage drop across the upper MOSFET's rDS(ON) using the OCSET pin and an internal 200 µA current source. This architecture reduces component count, board area, and conduction losses compared to shunt-based sensing methods.
How is the output voltage programmed on the HIP6004DCR-T?
The output voltage of the HIP6004DCR-T is programmed via five TTL-compatible VID input pins (VID0–VID4), which feed a built-in 5-bit DAC. These pins select one of 32 discrete output voltages from 1.100 V to 1.850 V in 25 mV increments. The DACOUT voltage also sets the PGOOD and OVP thresholds, ensuring coordinated regulation and protection.
What protection features does the HIP6004DCR-T provide?
The HIP6004DCR-T provides overvoltage protection (OVP) that disables PWM and asserts the OVP pin to trigger an external SCR crowbar at 115–120% of DACOUT, plus overcurrent protection (OCP) that cycles soft-start in hiccup mode using rDS(ON) sensing. It also includes power-good monitoring with ±10% window and 2% hysteresis, and internal power-on reset (POR) for reliable startup sequencing.
Can the HIP6004DCR-T operate with a +5V input supply?
Yes, the HIP6004DCR-T supports operation from either +5 V or +12 V bias supply on the VCC pin, with recommended operating conditions specifying +12 V ±10%. When using +5 V, ensure sufficient gate drive margin for the upper MOSFET - the UGATE driver delivers 350–500 mA source current, and BOOT voltage generation must be verified for proper high-side FET enhancement under low-input conditions.
