Product details
Overview
HIP6004DCB 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 1.10–1.85V output regulation (±1% over line/temperature), supports 50kHz–1MHz programmable switching frequency, and integrates voltage-mode control with 15MHz gain-bandwidth error amplifier for fast transient response in K7™ and similar CPU core supply applications.
For engineers reviewing the HIP6004DCB datasheet, HIP6004DCB pinout, HIP6004DCB application, or HIP6004DCB equivalent, key selection considerations include its 20-pin SOIC package, TTL-compatible 5-bit VID interface, rDS(ON)-based overcurrent sensing, PGOOD window comparator (±10%), and dual gate drivers optimized for high-efficiency DC-DC conversion in space-constrained embedded systems.
Technical Context
The HIP6004DCB implements voltage-mode PWM control using a 200kHz free-running oscillator adjustable via external RT resistor, enabling stable operation from 50kHz to >1MHz. Its error amplifier provides 15MHz gain-bandwidth and 6V/µs slew rate to support high-loop bandwidth for rapid load transients.
It integrates a 5-bit TTL-compatible DAC (VID0–VID4) that sets DACOUT from 1.100V to 1.850V in 25mV steps, directly defining output voltage, PGOOD thresholds (106%/89% of DACOUT), and OVP trip point (115% of DACOUT). Overcurrent protection uses the upper MOSFET's rDS(ON) with an internal 200µA current source at OCSET pin, eliminating external sense resistors.
Key Specifications

Pinout & Package
The HIP6004DCB is housed in a 20-lead SOIC package (JEDEC MS-013AC, pkg drawing M20.3), with exposed pad not present - standard plastic SOIC footprint suitable for reflow and wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSEN (1) | Output voltage feedback input | Connects directly to converter output; feeds PGOOD and OVP comparators to monitor regulation status and initiate protection. |
| OCSET (2) | Overcurrent threshold programming | Accepts resistor to upper MOSFET drain; sets IPEAK trip point using internal 200µA current source and rDS(ON) sensing. |
| SS (3) | Soft-start timing node | External capacitor (CSS) sets soft-start interval via internal 10µA current source; prevents inrush current during power-up. |
| VID0–VID4 (4–8) | Digital voltage identification inputs | TTL-compatible 5-bit bus; programs DACOUT reference and thus output voltage, PGOOD, and OVP thresholds. |
| COMP (9) | Error amplifier output | Drives compensation network; clamped during soft-start; interfaces with external RCZ network for loop stability. |
| FB (10) | Error amplifier inverting input | Connects to VSEN through divider or directly; completes voltage-mode feedback loop with COMP. |
| GND (11) | Signal ground reference | Reference point for all analog circuitry; must be low-impedance connection to minimize noise coupling. |
| PGOOD (12) | Open-collector power-good indicator | Asserts low when VSEN is outside ±10% of DACOUT; high during disable (VID=11111) or normal regulation. |
| PHASE (13) | High-side switch node monitor | Connects to upper MOSFET source; provides return path for UGATE and enables rDS(ON)-based overcurrent detection. |
| UGATE (14) | Upper MOSFET gate driver output | Drives gate of high-side N-MOSFET; requires bootstrap capacitor (BOOT–PHASE) for high-side floating bias. |
| BOOT (15) | Bootstrap supply input | Provides floating bias for UGATE driver; connected to PHASE via ceramic capacitor for charge pump operation. |
| PGND (16) | Power ground return | Low-impedance return for lower MOSFET source and power-stage currents; separate from signal GND to reduce noise. |
| LGATE (17) | Lower MOSFET gate driver output | Drives gate of synchronous rectifier (low-side N-MOSFET); referenced to PGND for direct drive capability. |
| VCC (18) | Bias supply input | Accepts +12V ±10% (or +5V) supply; powers internal logic, gate drivers, and reference circuits. |
| OVP (19) | Overvoltage fault output | Active-high open-drain output; drives external SCR to crowbar input rail upon 15% overvoltage condition. |
| 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 |
|---|---|---|---|
| HIP6006CB | Same 20-pin SOIC package; adds enable pin and enhanced thermal shutdown; identical VID range and regulation spec. | Supports remote ON/OFF control and tighter thermal fault response; suited for systems requiring active power management. | Select HIP6006CB when system-level enable functionality or improved thermal protection is required; otherwise HIP6004DCB remains optimal for cost-sensitive K7™-class designs. |

FAQ
What is the recommended input voltage range for HIP6004DCB?
The HIP6004DCB is specified for a +12V ±10% bias supply at the VCC pin, though the datasheet confirms operation from +5V or +12V input. Absolute maximum VCC is +15V. For reliable startup, the rising VCC threshold is 10.4V and falling threshold is 8.2V, so stable 12V rail regulation is critical. The HIP6004DCB does not regulate the VCC supply itself-it relies on clean, well-decoupled external bias.
How does HIP6004DCB implement overcurrent protection without a sense resistor?
The HIP6004DCB uses the upper MOSFET's rDS(ON) as the current-sensing element. An internal 200µA current source at the OCSET pin develops a voltage across an external ROCSET resistor, which is compared to the voltage drop across the MOSFET's channel (VPHASE–VSEN). When the latter exceeds the former, overcurrent is detected. This method eliminates the power loss and board area of a discrete shunt resistor, and is explicitly validated for the HIP6004DCB in the FN4855 datasheet.
Can HIP6004DCB be used with a 5V input instead of 12V?
Yes-the HIP6004DCB datasheet explicitly states it operates from either +5V or +12V input. However, gate drive performance differs: UGATE source current drops from 500mA (at 12V) to ~350mA (at 5V), and BOOT voltage headroom is reduced. For 5V input, ensure the upper MOSFET has sufficiently low VGS(th) and Qg to turn on fully, and verify boot capacitor sizing per Figure 6 guidelines. The HIP6004DCB's internal references and VID DAC remain accurate regardless of VCC level.
What is the function of the '11111' VID code on HIP6004DCB?
When VID0–VID4 are all driven high ('11111'), the HIP6004DCB disables its gate drivers and forces 0V output, activating Power-On Reset behavior. Uniquely, PGOOD asserts high in this state-unlike normal operation where PGOOD is low during fault or undervoltage. This deliberate inversion enables AND-ing of PGOOD signals in dual-CPU systems. The HIP6004DCB datasheet confirms this behavior is intentional and documented in Table 1 and Functional Description sections.
Does HIP6004DCB support external synchronization of its switching frequency?
No-the HIP6004DCB does not support external clock synchronization. Its oscillator is free-running and programmable only via the RT pin resistor (to GND or VCC). The datasheet specifies no SYNC, CLKIN, or external clock input functionality. Frequency adjustment is strictly analog: RT-to-GND raises frequency (≈200kHz + 5×10⁶/RT), RT-to-VCC lowers it (≈200kHz – 4×10⁷/RT). Systems requiring synchronized switching must use alternative controllers such as the HIP6006 or ISL6522 series.
