Product details
Overview
HIP6004BCVZ-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 voltage-mode regulation (±1% over line/temperature), 5-bit TTL-compatible DAC-based output voltage selection (1.3V–3.5V), and integrated overvoltage/overcurrent protection using MOSFET rDS(ON) sensing - deployed in Pentium Pro, PowerPC™, and K6™ CPU VRMs.
For engineers reviewing the HIP6004BCVZ-T datasheet, HIP6004BCVZ-T pinout, HIP6004BCVZ-T application, or HIP6004BCVZ-T equivalent, key selection considerations include its 200kHz free-running oscillator (adjustable 50kHz–1MHz), 15MHz error amplifier GBW, 0%–100% duty cycle range, PGOOD window comparator (±10%), and TSSOP-20 Pb-free RoHS-compliant package.
Technical Context
The HIP6004BCVZ-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. 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) (sensed at PHASE) against a reference set by OCSET current (200µA typ.) and external ROCSET resistor - eliminating need for a sense resistor. Output voltage is programmed via VID0–VID4 pins controlling a 5-bit DAC (DACOUT), which also sets PGOOD and OVP thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology | Synchronous-rectified buck PWM controller - drives two N-channel MOSFETs without external gate drivers. |
| Output Voltage Range | 1.3VDC to 3.5VDC in discrete steps: 0.05V increments (1.3–2.05V), 0.1V increments (2.1–3.5V) - set by 5-bit TTL VID inputs. |
| Regulation Accuracy | ±1% over line voltage and temperature - enables stable core voltage delivery for high-speed CPUs. |
| Oscillator Frequency | 200kHz nominal (free-running); adjustable from <50kHz to >1MHz via RT resistor - supports layout-optimized switching frequency selection. |
| Error Amplifier GBW | 15MHz gain-bandwidth product - enables high-loop bandwidth for sub-microsecond load transient recovery. |
| PGOOD Threshold | ±10% window around DACOUT voltage - provides reliable power-good signaling for CPU reset sequencing. |

Pinout & Package
Package: 20-lead TSSOP (Pb-free, RoHS-compliant), JEDEC MO-220 compliant, 4.4mm × 6.5mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSEN (1) | Output voltage feedback input | Connects directly to converter output; used by PGOOD and OVP comparators for monitoring and protection. |
| OCSET (2) | Overcurrent threshold programming | External resistor (ROCSET) sets trip point using internal 200µA current source and upper MOSFET rDS(ON). |
| SS (3) | Soft-start timing node | 10µA internal current source charges external capacitor to control startup ramp time and prevent inrush. |
| VID0–VID4 (4–8) | DAC digital inputs | TTL-compatible 5-bit bus selects DACOUT voltage (1.3–3.5V) - also defines PGOOD/OVP thresholds. |
| COMP (9) | Error amplifier output | Provides compensated feedback signal to PWM comparator; connects to external compensation network. |
| FB (10) | Error amplifier inverting input | Connects to voltage divider from VOUT; forms closed-loop regulation path with COMP and internal reference. |
| GND (11) | Signal ground reference | Reference point for all internal analog circuitry and logic thresholds - must be low-impedance connection. |
| PGOOD (12) | Open-drain status output | Asserts low when VSEN is outside ±10% of DACOUT; high during disable ('11111' VID code) or valid regulation. |
| PHASE (13) | High-side switch source monitor | Connects to upper MOSFET source; senses rDS(ON) voltage drop for overcurrent protection and boot return path. |
| UGATE (14) | Upper MOSFET gate driver output | Drives gate of high-side N-MOSFET; requires bootstrap supply (BOOT) for full enhancement. |
| BOOT (15) | Bootstrap supply input | Provides floating bias for UGATE driver; typically connected via capacitor from PHASE to BOOT. |
| PGND (16) | Power ground return | Low-impedance return path for lower MOSFET source and power-stage currents - separate from signal GND. |
| LGATE (17) | Lower MOSFET gate driver output | Drives gate of synchronous rectifier (low-side N-MOSFET); referenced to PGND. |
| VCC (18) | Bias supply input | Accepts +12V ±10% (or +5V) supply for internal circuitry and gate drivers - not derived from PHASE. |
| OVP (19) | Overvoltage crowbar trigger | Open-collector output that sources ≥60mA to drive external SCR during >115% DACOUT overvoltage event. |
| RT (20) | Oscillator frequency programming | Resistor to GND increases frequency (~200kHz + 5×10⁶/RT); resistor to VCC decreases frequency (~200kHz – 4×10⁷/RT). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HIP6006BCBZ-T | Same architecture but SOIC-20 package; lacks QFN/TSSOP thermal performance (θJA = 65°C/W vs. 85°C/W for TSSOP). | Preferred for legacy through-hole or larger-board designs where thermal margin is less constrained. | Select HIP6006BCBZ-T only if SOIC footprint compatibility is required and thermal derating can be accommodated. |
| ISL6522CBZ-T | Successor generation: higher GBW (20MHz), improved DAC resolution (6-bit), wider VOUT range (0.9–5.5V), and enhanced OVP response. | Supports newer CPU families (Pentium 4, Athlon XP) with lower VDD and faster transients - not backward-pin-compatible. | Choose ISL6522CBZ-T for new designs targeting higher performance or extended voltage range; HIP6004BCVZ-T remains suitable for legacy Pentium Pro/K6 systems. |
Compared with HIP6006BCBZ-T, HIP6004BCVZ-T offers superior thermal performance in TSSOP packaging for compact layouts, while ISL6522CBZ-T provides architectural upgrades including 6-bit DAC and 20MHz GBW - making it a functional upgrade rather than drop-in replacement.

FAQ
What is the recommended input supply voltage range for the HIP6004BCVZ-T?
The HIP6004BCVZ-T operates from a +12V ±10% supply (10.8V to 13.2V) applied to the VCC pin; it also supports +5V operation per datasheet specifications. The device is not rated for continuous operation outside this range, and absolute maximum VCC is +15V. Always decouple VCC to GND with a local ceramic capacitor (e.g., 1µF X7R) placed near the VCC and GND pins to suppress switching noise.
How does the HIP6004BCVZ-T implement overcurrent protection without a sense resistor?
The HIP6004BCVZ-T uses the upper MOSFET's intrinsic rDS(ON) as a current-sense element. An internal 200µA current source flows through an external ROCSET resistor connected to OCSET, generating a reference voltage. When the voltage drop across the upper MOSFET (measured between PHASE and VCC) exceeds this reference, the HIP6004BCVZ-T initiates hiccup-mode soft-start recovery - eliminating need for a discrete sense resistor and associated power loss.
Can the HIP6004BCVZ-T be used with modern CPUs requiring lower than 1.3V core voltage?
No - the HIP6004BCVZ-T's 5-bit DAC limits output voltage to a minimum of 1.3VDC (VID = '01111'). It was designed for Pentium Pro, K6™, and PowerPC™ processors of the late 1990s, which required 1.3–3.5V. For sub-1.3V applications (e.g., Core i-series, Ryzen), newer controllers like ISL6522CBZ-T or ISL95836 are required, as they support 0.9V–5.5V ranges and enhanced DAC resolution.
What is the function of the '11111' VID code on the HIP6004BCVZ-T?
When VID0–VID4 are all driven high ('11111'), the HIP6004BCVZ-T disables PWM gate drive outputs (UGATE/LGATE) and forces 0V DACOUT, activating Power-On Reset behavior. Unlike normal operation, PGOOD asserts high in this state - enabling logical AND-ing of PGOOD signals in dual-CPU systems where coordinated power-good assertion is required before system release from reset.
Does the HIP6004BCVZ-T support adjustable switching frequency, and how is it configured?
Yes - the HIP6004BCVZ-T features a programmable oscillator via the RT pin. Connecting a resistor from RT to GND increases frequency above 200kHz (Fs ≈ 200kHz + 5×10⁶/RT), while connecting RT to VCC decreases it (Fs ≈ 200kHz – 4×10⁷/RT). This allows tuning from below 50kHz to over 1MHz, enabling optimization for EMI compliance, efficiency, or component size constraints in the final HIP6004BCVZ-T design.
