Product details
Overview
HIP6004BCVZA-T from Intersil is a synchronous-rectified buck PWM controller IC designed to drive two N-channel MOSFETs in high-performance microprocessor power supplies. It delivers precise output voltage regulation (±1% over line/temperature), supports 1.3V–3.5V DAC-programmed outputs in 0.05V/0.1V steps, features a 200kHz free-running oscillator adjustable from 50kHz to >1MHz, and integrates overvoltage/overcurrent protection using MOSFET rDS(ON) sensing - deployed in Pentium Pro, PowerPC™, and K6™ CPU VRMs.
For engineers reviewing the HIP6004BCVZA-T datasheet, HIP6004BCVZA-T pinout, HIP6004BCVZA-T application, or HIP6004BCVZA-T equivalent, key selection considerations include its TTL-compatible 5-bit VID interface, voltage-mode control with 15MHz GBW error amplifier, 0–100% duty cycle capability, PGOOD window monitoring (±10%), and TSSOP-20 Pb-free RoHS-compliant packaging for compact DC-DC regulator designs.
Technical Context
The HIP6004BCVZA-T implements voltage-mode PWM control with a single feedback loop, using an internal 200kHz triangle-wave oscillator programmable via RT-to-GND or RT-to-VCC resistors. Its error amplifier provides 15MHz gain-bandwidth and 6V/µs slew rate to support fast transient response in microprocessor VRMs.
Overcurrent protection operates by comparing the voltage drop across the upper MOSFET's rDS(ON) (monitored at PHASE) against a reference set by OCSET current (200µA typ.) and external ROCSET resistor. Overvoltage protection triggers OVP pin assertion at 115–120% of DACOUT and disables PWM while enabling external SCR crowbar.

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HIP6006BCBZ-T | Same family; adds adaptive voltage positioning (AVP) and enhanced thermal shutdown; 24-pin SOIC package | Targeted for newer Pentium 4-era CPUs requiring AVP; not pin-compatible with HIP6004BCVZA-T | Select only if AVP and higher thermal protection are required; requires PCB redesign due to different pin count and layout |

FAQ
What is the recommended operating supply voltage for HIP6004BCVZA-T?
The HIP6004BCVZA-T is specified for +12V ±10% VCC operation, compatible with standard ATX 12V rails. It does not require a separate +5V bias supply. Absolute maximum VCC is +15V; operation outside the recommended range may cause improper DAC output, unstable PWM, or latch-up. Always decouple VCC to PGND with a local 10µF ceramic capacitor placed near pins 18 and 16.
How does HIP6004BCVZA-T implement overcurrent protection without a sense resistor?
HIP6004BCVZA-T uses the upper MOSFET's rDS(ON) as the current-sensing element. An internal 200µA current source pulls down OCSET (pin 2), developing a voltage across external ROCSET that is compared to the PHASE-to-VIN voltage drop. When the MOSFET's on-resistance voltage exceeds this threshold, the controller initiates hiccup-mode soft-start recovery. This eliminates sense resistor losses and PCB space while maintaining ±15% trip accuracy.
Can HIP6004BCVZA-T be used with a 5V input supply instead of 12V?
Yes - the HIP6004BCVZA-T supports operation from either +5V or +12V input, as confirmed in the datasheet's "Operating Conditions" and "Functional Description" sections. When using +5V, ensure VCC is supplied from that rail and verify gate drive margins for the selected MOSFETs; UGATE and LGATE performance remains fully specified at VCC = 5V, though peak source current reduces slightly versus 12V operation.
What is the function of the '11111' VID code on HIP6004BCVZA-T?
The '11111' VID code (all VID pins high) forces DACOUT to 0V, disabling the PWM gate drivers and halting converter operation. Unlike other codes, it asserts PGOOD high - a deliberate feature enabling AND-gating of PGOOD signals in dual-CPU systems. This behavior is explicitly documented in the datasheet's "Output Voltage Program" section and must be accounted for in power-sequencing firmware.
Does HIP6004BCVZA-T support adjustable switching frequency, and how is it configured?
Yes - HIP6004BCVZA-T features a programmable oscillator via the RT pin (20). Connecting a resistor from RT to GND increases frequency above 200kHz (e.g., 100kΩ → ~500kHz); connecting RT to VCC decreases frequency (e.g., 100kΩ → ~100kHz). The exact relationship follows published equations in the datasheet, and frequency variation is ±15% over the full RT range. This allows optimization for EMI, efficiency, or component size.
