Product details
Overview
HIP6004BCV 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 and PowerPC™ CPU VRMs.
For engineers reviewing the HIP6004BCV datasheet, HIP6004BCV pinout, HIP6004BCV application, or HIP6004BCV equivalent, key selection considerations include its TSSOP-20 package, VID0–VID4 digital voltage programming interface, voltage-mode control architecture with 15MHz error amplifier GBW, and absence of external current-sense resistor requirement.
Technical Context
The HIP6004BCV implements voltage-mode PWM control with a single feedback loop, using an internal 15MHz gain-bandwidth error amplifier and 6V/µs slew rate to achieve fast transient response. Its oscillator frequency is set via external RT resistor (50kHz–1MHz range), and duty cycle spans 0%–100%.
Overcurrent protection operates by comparing voltage across the upper MOSFET's rDS(ON) against a reference derived from OCSET pin current (200µA typical) and ROCSET resistor; overvoltage protection triggers at 115%–120% of DACOUT and asserts OVP pin to drive external SCR. PGOOD monitors VSEN against DACOUT with ±10% window and 2% hysteresis.

Pinout & Package
HIP6004BCV is packaged in a 20-lead TSSOP (Moisture Sensitivity Level not specified; JEDEC-compliant footprint per pkg drawing M20.173).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSEN (1) | Output voltage sense input | Connects directly to regulated output; feeds PGOOD comparator and OVP circuit - enables accurate monitoring without divider network. |
| OCSET (2) | Overcurrent threshold programming | 200µA current source sets trip point with ROCSET resistor and upper MOSFET rDS(ON); initiates hiccup-mode soft-start on fault. |
| SS (3) | Soft-start timing node | 10µA internal current source charges external CSS capacitor to 4V - controls ramp-up time and prevents inrush current. |
| VID0–VID4 (4–8) | Digital voltage identification inputs | TTL-compatible 5-bit bus selects DACOUT reference (1.3V–3.5V); defines both output voltage and PGOOD/OVP thresholds. |
| COMP (9) | Error amplifier output | Drives compensation network; connects to FB through external RC components - forms voltage-mode control loop integrator. |
| FB (10) | Error amplifier inverting input | Connects to DACOUT internally; external feedback not used - simplifies design versus traditional error amp configurations. |
| GND (11) | Signal ground reference | Reference for all analog and logic signals; separate from PGND to avoid noise coupling into sensitive circuits. |
| PGOOD (12) | Open-drain power-good indicator | Asserts low when VSEN is outside ±10% of DACOUT; high during disable (VID=11111) - supports system sequencing and fault reporting. |
| PHASE (13) | High-side MOSFET source monitor | Provides return path for UGATE drive and senses voltage drop across Q1 for rDS(ON)-based overcurrent detection. |
| UGATE (14) | High-side gate driver output | Supplies 350–500mA peak source/sink current - drives N-MOSFET gates directly without external buffer. |
| BOOT (15) | Bootstrap supply for high-side driver | Requires external bootstrap capacitor between BOOT and PHASE - enables floating gate drive for high-side N-MOSFET. |
| PGND (16) | Power ground return | Low-impedance return for LGATE and MOSFET sources - must be connected to PCB power plane near Q1/Q2. |
| LGATE (17) | Low-side gate driver output | Supplies 300–450mA peak source/sink current - optimized for synchronous rectification with minimal dead-time requirements. |
| VCC (18) | Bias supply input | Accepts +12V ±10%; powers internal logic, drivers, and references - no +5V operation supported. |
| OVP (19) | Overvoltage protection output | Open-drain output sourcing ≥60mA when VSEN exceeds 115% DACOUT - intended to trigger external SCR crowbar. |
| RT (20) | Oscillator frequency programming | Resistor to GND increases frequency (Fs ≈ 200kHz + 5×10⁶/RT); resistor to VCC decreases it (Fs ≈ 200kHz – 4×10⁷/RT). |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HIP6006BCB | SOIC-20 package; identical electrical specs and pinout except OCSET threshold is fixed at 1.26V (vs. programmable via ROCSET on HIP6004BCV). | Lacks rDS(ON)-based overcurrent adjustability - requires external sense resistor for current limiting in most implementations. | Select HIP6006BCB only if fixed-threshold overcurrent protection suffices and SOIC-20 footprint is preferred. |
| ISL6522CBZ | QFN-20 package; adds adaptive voltage positioning (AVP), supports 300kHz–1.5MHz frequency, and includes integrated MOSFET drivers with higher peak current (1.2A sink/source). | Designed for newer Pentium 4 and Athlon XP platforms with tighter transient response requirements and AVP support. | Choose ISL6522CBZ when upgrading legacy designs needing enhanced transient performance and AVP capability. |
Compared with HIP6006BCB, HIP6004BCV offers field-adjustable overcurrent trip via ROCSET while sharing identical control architecture; versus ISL6522CBZ, it lacks AVP and has lower gate drive strength but maintains full compatibility with Pentium Pro/PowerPC™ VID tables and legacy layouts.

FAQ
What is the operating temperature range for the HIP6004BCV?
The HIP6004BCV is rated for an ambient temperature range of 0°C to 70°C, as confirmed in the Ordering Information table on page 2 of FN4567 Rev 3.00. This commercial-grade specification aligns with its target use in desktop and embedded microprocessor power supplies where airflow and thermal management are controlled. The HIP6004BCV does not support extended or industrial temperature ranges.
Does the HIP6004BCV require an external current-sense resistor?
No, the HIP6004BCV 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 the need for a discrete sense resistor, reducing power loss and board space - a key design feature documented in the Functional Description and Over-Current Protection sections of the HIP6004BCV datasheet.
What package type is used for the HIP6004BCV?
The HIP6004BCV uses a 20-lead TSSOP package, as explicitly stated in the Ordering Information table (page 2 of FN4567 Rev 3.00) and confirmed by the "HIP6004BCV" part number suffix and pkg drawing M20.173. This surface-mount package provides a smaller footprint than the SOIC variant (HIP6004BCB) and is RoHS-compliant when ordered with the 'Z' suffix (e.g., HIP6004BCVZ).
Can the HIP6004BCV operate from a +5V supply?
No, the HIP6004BCV cannot operate from a +5V supply. Its recommended operating condition specifies a VCC supply voltage of +12V ±10%, and the Absolute Maximum Ratings list VCC up to +15V. The datasheet states "Operates from +5V or +12V Input" in the Features section, but the Electrical Specifications table and Operating Conditions section exclusively define +12V ±10% as the valid supply - confirming +5V operation is not supported for the HIP6004BCV.
How is the output voltage programmed on the HIP6004BCV?
The output voltage of the HIP6004BCV is programmed using five TTL-compatible VID input pins (VID0–VID4) that feed a built-in 5-bit DAC. These pins select DACOUT voltage levels from 1.3V to 3.5V in discrete steps: 0.05V increments from 1.3V to 2.05V, and 0.1V increments from 2.1V to 3.5V. Table 1 on page 8 of FN4567 Rev 3.00 lists all 32 combinations and corresponding DACOUT values - the selected DACOUT directly sets both the regulated output voltage and PGOOD/OVP thresholds.
