Product details
Overview
HIP6004ECB-T from Renesas (formerly Intersil) is a synchronous-rectified buck PWM controller with integrated output voltage monitoring, designed to drive two N-channel MOSFETs in high-performance microprocessor VRM8.5 power supplies. It delivers 1.05V–1.825V output via 5-bit VID DAC (25mV steps), achieves ±1% regulation over line/temperature, and features 15MHz GBWP error amplifier, 200kHz programmable oscillator (50kHz–1MHz), and rDS(ON)-based overcurrent sensing.
For engineers reviewing the HIP6004ECB-T datasheet, HIP6004ECB-T pinout, HIP6004ECB-T application, or HIP6004ECB-T equivalent, key selection considerations include its voltage-mode control architecture, single-loop stability, 0–100% duty cycle range, PGOOD window comparator (±10%), and OVP-triggered external SCR crowbar capability for high-reliability DC-DC systems.
Technical Context
The HIP6004ECB-T implements voltage-mode PWM control using a 200kHz free-running triangle-wave oscillator adjustable via RT-to-GND or RT-to-VCC resistor networks. Its error amplifier provides 15MHz gain-bandwidth and 6V/µs slew rate to support fast transient response in microprocessor core supplies.
Overcurrent protection operates without a sense resistor by comparing the upper MOSFET's VPHASE–VOCSET drop against a 200µA current source × ROCSET, triggering hiccup-mode soft-start restart. Output voltage monitoring uses DACOUT as reference for both PGOOD (106%/89% thresholds, 2% hysteresis) and OVP (115% trip).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Range | 1.05V–1.825V in 25mV binary steps via 5-bit VID inputs; sets DACOUT reference for regulation, PGOOD, and OVP. |
| Voltage Regulation Accuracy | ±1% over temperature and line variations; ensures stable core supply under dynamic load and thermal stress. |

| FB (10) | Error amplifier inverting input | Connects to VSEN via RC network; forms voltage-mode feedback loop with COMP and internal reference. |
| GND (11) | Signal ground reference | Common return for all analog and logic circuitry; must be separated from PGND to avoid noise coupling. |
| PGOOD (12) | Open-drain status indicator | Pulled low when VSEN is outside ±10% of DACOUT; used for system power sequencing and fault reporting. |
| PHASE (13) | High-side switch node monitor | Connects to upper MOSFET source; provides return path for UGATE drive and rDS(ON) voltage sensing for OC protection. |

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-T | Same 20-pin SOIC package, 5-bit VID, ±1% regulation, but uses current-mode control and lacks OVP crowbar output. | Requires external overvoltage latch; better suited for applications prioritizing current-loop stability over fail-safe crowbar protection. | Select ISL6522CBZ-T when current-mode control simplifies compensation and external SCR crowbar is not required. |
| RT8802AGQW | 6-bit VID (12.5mV steps), integrated MOSFET drivers with 1.2A peak, but no rDS(ON) OC sensing-requires external sense resistor. | Higher resolution VID and stronger drivers support newer CPU cores, but adds BOM cost and layout complexity for current sensing. | Choose RT8802AGQW for advanced processors needing finer voltage granularity and higher gate drive strength, accepting added sensing components. |
Compared with ISL6522CBZ-T and RT8802AGQW, the HIP6004ECB-T uniquely combines voltage-mode simplicity, rDS(ON) current sensing, and hardware OVP crowbar in a mature, production-proven VRM8.5 solution-making it optimal for cost-sensitive, reliability-critical legacy microprocessor platforms.

FAQ
What is the maximum switching frequency supported by the HIP6004ECB-T?
The HIP6004ECB-T supports a programmable switching frequency ranging from below 50kHz to over 1MHz, with a nominal free-running frequency of 200kHz. The actual frequency is set by an external resistor (RT) connected either to GND (to increase frequency) or to VCC (to decrease frequency), per the equations provided in the datasheet. This wide range allows designers to balance efficiency, magnetics size, and EMI performance for specific application needs.
Does the HIP6004ECB-T require an external current-sense resistor for overcurrent protection?
No, the HIP6004ECB-T 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 method eliminates the power loss and board space associated with a discrete sense resistor while maintaining accurate current limiting for the HIP6004ECB-T's target applications.
How is the output voltage programmed on the HIP6004ECB-T?
The output voltage of the HIP6004ECB-T is programmed via five TTL-compatible VID input pins (VID25mV, VID0–VID3), which configure a 5-bit DAC to generate DACOUT - a precision reference voltage ranging from 1.05V to 1.825V in 25mV increments. This DACOUT voltage directly sets the regulated output, PGOOD thresholds, and OVP trip point. The HIP6004ECB-T datasheet includes Table 1 listing all 32 VID code combinations and corresponding DACOUT values.
What protection features are integrated into the HIP6004ECB-T?
The HIP6004ECB-T integrates multiple hardware-based protections: overvoltage protection (OVP) with 115% DACOUT trip and active-high OVP pin to trigger an external SCR crowbar; overcurrent protection (OCP) using rDS(ON) sensing and hiccup-mode soft-start restart; power-good monitoring with ±10% window and 2% hysteresis; and power-on reset (POR) that monitors VCC and OCSET to ensure proper initialization. These functions operate autonomously without firmware or external supervision.
Can the HIP6004ECB-T be used with a +5V input supply instead of +12V?
Yes, the HIP6004ECB-T is specified to operate from either +5V or +12V input supplies, as stated in the datasheet Features section and Operating Conditions table. When using +5V, the VCC pin must be supplied with +5V ±10%, and the gate drive performance (UGATE/LGATE source/sink current) remains fully functional. However, the BOOT circuit requires sufficient headroom to drive the upper MOSFET gate above PHASE, so appropriate bootstrap capacitor sizing and MOSFET VGS rating must be verified for +5V operation in the HIP6004ECB-T design.
