Product details
Overview
HIP6004DCBZ-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 HIP6004DCBZ-T datasheet, HIP6004DCBZ-T pinout, HIP6004DCBZ-T application, or HIP6004DCBZ-T equivalent, this page provides verified functional role, confirmed SOIC-20 pin mapping, real-world transient response metrics, validated protection thresholds, and documented alternative options for high-current DC-DC converter design.
Technical Context
The HIP6004DCBZ-T implements voltage-mode PWM control using a 15MHz gain-bandwidth error amplifier and 6V/µs slew rate to achieve fast transient response. Its 200kHz free-running oscillator is adjustable via external RT resistor, enabling stable operation from 50kHz to >1MHz.
It integrates a TTL-compatible 5-bit DAC (VID0–VID4) that sets both output voltage and PGOOD/OVP thresholds, while overcurrent protection uses the upper MOSFET's rDS(ON)-eliminating external sense resistors-and triggers hiccup-mode soft-start recovery.

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL6522CBZ-T | Same manufacturer, pin-compatible SOIC-20; adds adaptive voltage positioning (AVP) and enhanced thermal shutdown | Targeted at newer Pentium 4-era VRMs requiring AVP; lacks '11111' VID disable mode | Select ISL6522CBZ-T if AVP support and tighter thermal protection are required for post-2003 CPU platforms |

FAQ
What is the function of the OCSET pin on the HIP6004DCBZ-T?
The OCSET pin on the HIP6004DCBZ-T connects to an external resistor (ROCSET) and the drain of the upper MOSFET to implement rDS(ON)-based overcurrent protection. An internal 200µA current source develops a voltage across ROCSET, and when the voltage drop across the upper MOSFET exceeds that value, the HIP6004DCBZ-T initiates hiccup-mode soft-start recovery. This eliminates the need for a discrete current-sense resistor and reduces power loss.
Does the HIP6004DCBZ-T support both +5V and +12V bias supplies?
The HIP6004DCBZ-T is specified to operate from a +12V ±10% VCC supply. While the datasheet notes "Operates from +5V or +12V Input" in features, the Recommended Operating Conditions table explicitly lists VCC = +12V ±10%, and Absolute Maximum Ratings define VCC ≤ +15V. The +5V input reference applies to the main converter input (VIN), not the IC bias rail. Therefore, HIP6004DCBZ-T requires +12V on VCC (Pin 18) for proper operation.
How does the HIP6004DCBZ-T generate its Power-Good signal?
The HIP6004DCBZ-T generates the PGOOD signal using an internal window comparator that monitors VSEN against DACOUT. PGOOD asserts high when VSEN is within ±10% of DACOUT, with 2% hysteresis to prevent oscillation due to output ripple. During the '11111' VID combination, PGOOD remains high even though the controller is disabled-enabling AND-gating of multiple PGOOD signals in dual-CPU systems. The output is open-collector, requiring an external pull-up resistor.
Can the HIP6004DCBZ-T be used with QFN packages?
No-the HIP6004DCBZ-T is the SOIC-20 variant with Pb-free finish ('Z') and tape-and-reel packaging ('-T'). The QFN-20 version is designated HIP6004DCRZ-T. Although both share identical electrical functionality and pinout numbering, the physical package, thermal characteristics (θJA = 65°C/W for SOIC vs. 33°C/W for QFN), and PCB land pattern differ. Substituting HIP6004DCBZ-T for HIP6004DCRZ-T requires board redesign and is not mechanically compatible.
What is the purpose of the '11111' VID configuration on the HIP6004DCBZ-T?
The '11111' VID configuration (all VID0–VID4 pulled high) disables the HIP6004DCBZ-T gate drivers and forces 0V output, activating Power-On Reset behavior. Uniquely, PGOOD asserts high in this state-unlike normal operation where PGOOD is low during fault or disable. This allows safe AND-ing of PGOOD signals from two HIP6004DCBZ-T controllers in dual-microprocessor systems, ensuring system power-good only when both supplies are valid or both are intentionally held off.
