Product details
Overview
HIP6004BCV-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-based DC-DC regulators.
For engineers reviewing the HIP6004BCV-T datasheet, HIP6004BCV-T pinout, HIP6004BCV-T application, or HIP6004BCV-T equivalent, key selection considerations include its voltage-mode control architecture, TTL-compatible 5-bit VID interface, integrated PGOOD monitoring with ±10% window, gate driver sourcing/sinking capability (500mA/450mA), and TSSOP-20 package thermal performance (θJA = 85°C/W).
Technical Context
The HIP6004BCV-T implements voltage-mode PWM control with a 15MHz gain-bandwidth error amplifier and 6V/µs slew rate, enabling fast transient response in microprocessor VRMs. Its oscillator uses an external RT resistor to set switching frequency across a 50kHz–1MHz range, while the internal 200µA OCSET current source enables MOSFET rDS(ON)-based overcurrent detection without a sense resistor.
It integrates a 5-bit TTL-compatible DAC (VID0–VID4) that sets both output voltage (1.3V–3.5V) and associated protection thresholds (PGOOD, OVP). The PGOOD signal asserts low when VSEN deviates >±10% from DACOUT, with 2% hysteresis to prevent ripple-induced toggling.

The HIP6004BCV-T is housed in a 20-lead TSSOP package (JEDEC MO-220 compliant), optimized for thermal dissipation (θJA = 85°C/W) and board space efficiency in high-density CPU VRM layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSEN (1) | Output voltage feedback input | Connects to converter output to enable PGOOD assertion and OVP monitoring relative to DACOUT reference. |
| OCSET (2) | Overcurrent threshold programming | External resistor sets trip point using internal 200µA current source and upper MOSFET rDS(ON). |
| SS (3) | Soft-start timing node | 10µA internal current charges external capacitor to control ramp-up time and prevent inrush current. |
| VID0–VID4 (4–8) | Digital voltage identification inputs | TTL-compatible 5-bit bus selects DACOUT voltage level - determines output, PGOOD, and OVP thresholds. |
| COMP (9) | Error amplifier output | Drives external compensation network; connects to feedback loop compensation components. |
| FB (10) | Error amplifier inverting input | Connects to VSEN through resistive divider to close voltage regulation loop. |
| GND (11) | Signal ground reference | Reference point for all analog and digital logic levels; must be low-impedance connection to system ground plane. |

| UGATE (14) | Upper MOSFET gate driver output | Drives gate of high-side N-MOSFET; requires bootstrap circuitry for full enhancement. |
| BOOT (15) | Bootstrap supply input | Provides floating bias for UGATE driver; typically connected to PHASE via bootstrap diode/capacitor. |
| 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% input; powers internal circuitry and gate drivers - decoupling capacitor required. |
| OVP (19) | Overvoltage protection output | Active-high output triggers external SCR crowbar during >115% DACOUT overvoltage - disables PWM immediately. |
| RT (20) | Oscillator frequency programming | Resistor to GND increases frequency; resistor to VCC decreases frequency - enables precise switching frequency tuning. |

FAQ
What is the maximum supported switching frequency for the HIP6004BCV-T?
The HIP6004BCV-T supports a switching frequency range from 50kHz to over 1MHz, set by an external RT resistor. With RT connected to GND, frequency increases according to Fs ≈ 200kHz + 5×10⁶/RT(kΩ); with RT pulled up to VCC, it decreases per Fs ≈ 200kHz – 4×10⁷/RT(kΩ). The HIP6004BCV-T achieves stable operation at 1MHz in validated reference designs with appropriate gate drive and layout.
Does the HIP6004BCV-T require an external current-sense resistor for overcurrent protection?
No, the HIP6004BCV-T does not require an external current-sense resistor. It implements overcurrent protection using the upper MOSFET's rDS(ON) as the sensing element, combined with an internal 200µA current source on the OCSET pin and an external ROCSET resistor. This method eliminates added component cost and PCB area while maintaining accurate trip-point calibration per the equation IPEAK = (IOCSET × ROCSET)/rDS(ON).
What VID voltage levels does the HIP6004BCV-T support, and how are they selected?
The HIP6004BCV-T supports 32 discrete output voltage levels from 1.30V to 3.50V, selected via TTL-compatible logic states on VID0–VID4 pins (pins 4–8). Levels from 1.30V to 2.05V are spaced at 0.05V increments; from 2.10V to 3.50V at 0.10V increments. Each combination corresponds to a specific DACOUT voltage listed in Table 1 of the HIP6004BCV-T datasheet, which directly sets the regulated output and protection thresholds.
How does the HIP6004BCV-T generate the PGOOD signal, and what is its accuracy?
The HIP6004BCV-T generates the PGOOD signal using an internal window comparator that monitors VSEN against DACOUT. PGOOD asserts low when VSEN falls outside ±10% of DACOUT, with 2% hysteresis to prevent oscillation due to output ripple. The comparator reference tracks DACOUT directly, ensuring PGOOD accuracy remains tied to the ±1% voltage regulation tolerance of the HIP6004BCV-T's reference circuitry.
Can the HIP6004BCV-T operate with a +5V input supply instead of +12V?
Yes, the HIP6004BCV-T operates from either +5V or +12V input as specified in the Absolute Maximum Ratings and Operating Conditions. When using +5V, VCC must be supplied at 5V ±10%, and the gate drive capability (UGATE/LGATE sourcing/sinking) remains functional, though bootstrapping may require adjustment to ensure sufficient VBOOT–VPHASE margin for upper MOSFET enhancement. The HIP6004BCV-T's internal circuits are fully characterized across both supply ranges.
