Product details
Overview
HIP6004DCBZ from Intersil is a synchronous-rectified buck PWM controller with integrated voltage-mode regulation, 5-bit VID DAC, and output voltage monitoring for microprocessor power supplies. It drives two N-channel MOSFETs, delivers ±1% output voltage accuracy over temperature and line, supports 1.10–1.85V output in 25mV steps, and operates with 12V bias supply. It is used in K7™ and other high-performance CPU VRMs.
For engineers reviewing the HIP6004DCBZ datasheet, HIP6004DCBZ pinout, HIP6004DCBZ application, or HIP6004DCBZ equivalent, key selection criteria include its 200kHz free-running oscillator (adjustable 50kHz–1MHz), 15MHz error amplifier gain-bandwidth, 6V/µs slew rate, rDS(ON)-based current sensing, and ±10% PGOOD window with 2% hysteresis.
Technical Context
The HIP6004DCBZ implements voltage-mode PWM control using a single feedback loop with an internal 15MHz GBWP error amplifier and 6V/µs slew rate to achieve fast transient response. Its 200kHz triangle-wave oscillator is resistor-programmable across five decades (50kHz–1MHz) via RT pin, enabling optimization for efficiency or size.
It integrates a TTL-compatible 5-bit DAC (VID0–VID4) that sets DACOUT from 1.100V to 1.850V in 25mV increments, directly defining output voltage, PGOOD thresholds (±10%), and OVP trip point (115% of DACOUT). Overcurrent protection uses the upper MOSFET's rDS(ON) with external ROCSET, eliminating sense resistors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HIP6006CBZ | Same SOIC-20 package; adds adaptive voltage positioning (AVP) and enhanced thermal shutdown | Targeted for newer Athlon XP and Pentium 4 VRMs requiring AVP compliance | Choose HIP6006CBZ if AVP support and tighter thermal protection are required; not drop-in due to AVP pin mapping |
| ISL6522CBZ | Successor generation; higher 25MHz GBWP, 10V/µs slew rate, and integrated MOSFET drivers with 1.2A peak drive | Designed for Pentium M/Core Duo VRMs with faster transient requirements and lower VOUT down to 0.7V | Choose ISL6522CBZ for next-gen platforms needing >200kHz bandwidth and sub-1V operation; requires PCB redesign |
Compared with HIP6004DCBZ, HIP6006CBZ adds AVP functionality but retains pin compatibility for basic operation, while ISL6522CBZ offers significantly higher bandwidth and lower minimum output voltage at the cost of non-pin-compatible layout changes.

FAQ
What is the operating temperature range for the HIP6004DCBZ?
The HIP6004DCBZ is specified for operation from 0°C to +70°C ambient temperature. This commercial-grade range aligns with motherboard and embedded system environments where airflow and thermal design ensure junction temperatures remain below the absolute maximum of 150°C. The SOIC package has a θJA of 65°C/W under standard test conditions.
Does the HIP6004DCBZ require an external current-sense resistor?
No, the HIP6004DCBZ 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 external ROCSET resistor. This method reduces component count, board area, and power loss compared to shunt-based sensing.
How is the output voltage programmed on the HIP6004DCBZ?
The HIP6004DCBZ output voltage is programmed via five TTL-compatible VID pins (VID0–VID4) that feed a 5-bit internal DAC. These pins accept binary-coded inputs to select one of 32 discrete DACOUT levels from 1.100V to 1.850V in 25mV increments. The DACOUT voltage directly sets the target output, PGOOD thresholds, and OVP trip point.
What is the function of the RT pin on the HIP6004DCBZ?
The RT pin on the HIP6004DCBZ sets the switching frequency of the internal oscillator. Connecting a resistor from RT to GND increases frequency above the 200kHz nominal (e.g., 50kHz–1MHz range); connecting RT to VCC decreases it. The relationship follows Fs ≈ 200kHz + 5×10⁶/RT(kΩ) for pull-down and Fs ≈ 200kHz – 4×10⁷/RT(kΩ) for pull-up configurations.
Can the HIP6004DCBZ operate from a +5V supply instead of +12V?
No, the HIP6004DCBZ requires a +12V ±10% supply on the VCC pin for proper operation. While the datasheet notes the controller is "designed to operate from +5V or +12V input", this refers to the main converter input (VIN), not the bias supply. The VCC pin specification explicitly states +12V ±10% as the recommended operating condition, and absolute maximum rating is +15V.
