Product details
Overview
HIP6004ECB from Intersil is a synchronous-rectified buck PWM controller with integrated voltage-mode regulation, 5-bit VID DAC, and output voltage monitoring for microprocessor VRM8.5 applications. It drives two N-channel MOSFETs, delivers 1.05V–1.825V output in 25mV steps, maintains ±1% regulation over line/temperature, and features 15MHz GBWP error amplifier and 200kHz programmable oscillator (50kHz–1MHz).
For engineers reviewing the HIP6004ECB datasheet, HIP6004ECB pinout, HIP6004ECB application, or HIP6004ECB equivalent, key selection considerations include its rDS(ON)-based overcurrent sensing, PGOOD window comparator (±10%), OVP-triggered SCR crowbar, soft-start current source (10μA), and compatibility with +5V/+12V bias supplies.
Technical Context
The HIP6004ECB implements voltage-mode PWM control using a 200kHz free-running oscillator adjustable via RT pin, with ramp amplitude of 1.9VP-P. Its error amplifier delivers 15MHz gain-bandwidth and 6V/μs slew rate to support fast transient response in high-current microprocessor power delivery.
Overcurrent protection uses the upper MOSFET's rDS(ON) with an internal 200μA current source at OCSET pin; overvoltage protection triggers external SCR via OVP pin at 115–120% DACOUT. Power good status is asserted when VSEN is within ±10% of DACOUT, with 2% hysteresis.

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL6522CBZ | Same manufacturer (Intersil), 2-phase capable, higher gate drive current (1A), includes phase-interleaving logic | Targeted at higher-current dual-phase VRM designs; not drop-in compatible due to extra phase-control pins and different pinout | Select ISL6522CBZ only when scaling beyond single-phase current limits or requiring interleaved operation |
| TPS51116PWR | Texas Instruments part; supports 3-state VID, integrated MOSFET drivers with adaptive dead-time control, lower quiescent current | Designed for newer mobile VRM standards; lacks OVP crowbar output and uses different protection architecture | Choose TPS51116PWR for battery-powered or thermally constrained applications where adaptive timing and low IQ matter more than hardware crowbar |

FAQ
What is the operating temperature range for the HIP6004ECB?
The HIP6004ECB is specified for operation from 0°C to 70°C ambient temperature. This range aligns with commercial-grade requirements for desktop and embedded microprocessor power modules. Thermal resistance θJA is 65°C/W in the SOIC package, enabling reliable operation without forced airflow under typical load conditions. The HIP6004ECB incorporates internal power-on reset (POR) that monitors VCC and OCSET voltages to ensure safe initialization across this full temperature span.
How does the HIP6004ECB implement overcurrent protection without a sense resistor?
The HIP6004ECB uses the upper MOSFET's intrinsic rDS(ON) as the current-sensing element. An internal 200μA current source at the OCSET pin develops a voltage across an external ROCSET resistor; when the voltage drop across the MOSFET's rDS(ON) exceeds that across ROCSET, the HIP6004ECB initiates hiccup-mode soft-start recovery. This method eliminates discrete sense resistors, reducing power loss and PCB area while maintaining accurate overcurrent trip points calibrated to MOSFET characteristics.
Can the HIP6004ECB be used with a +5V bias supply instead of +12V?
Yes, the HIP6004ECB supports both +5V and +12V bias supplies on the VCC pin, as confirmed in the datasheet's "Features" and "Operating Conditions" sections. When using +5V, gate drive strength is reduced proportionally - UGATE source current drops to ~350mA and LGATE to ~300mA - but remains sufficient for logic-level MOSFETs. The oscillator frequency range and DAC accuracy are unaffected. Ensure VCC decoupling capacitance meets minimum requirements for stability under +5V operation.
What is the function of the VID25mV pin on the HIP6004ECB?
The VID25mV pin on the HIP6004ECB serves as the most significant bit (MSB) of the 5-bit VID DAC input, enabling 32 discrete output voltage settings from 1.05V to 1.825V in 25mV increments. Unlike standard VID0–VID3 pins, VID25mV determines whether the DAC operates in coarse (1.05–1.275V) or fine (1.30–1.825V) range. Its state (0 or 1) directly selects the base voltage offset for the internal DAC, ensuring precise VRM8.5-compliant core voltage programming for Pentium III and compatible processors.
Does the HIP6004ECB support adjustable switching frequency, and how is it configured?
Yes, the HIP6004ECB supports fully adjustable switching frequency from below 50kHz to over 1MHz using the RT pin. A resistor from RT to GND increases frequency above the nominal 200kHz (Fs ≈ 200kHz + 5×10⁶/RT); a resistor from RT to VCC decreases it (Fs ≈ 200kHz – 4×10⁷/RT). The RT pin maintains a stable 1.26V reference, allowing predictable frequency tuning. This configurability lets designers optimize trade-offs between magnetic size, efficiency, and EMI in the final HIP6004ECB-based power stage.
