Product details
Overview
HIP6004ECVZ from Renesas (formerly Intersil) is a synchronous-rectified buck PWM controller with integrated voltage-mode regulation, 5-bit DAC-based output voltage programming (1.05V–1.825V in 25mV steps), ±1% output regulation over line/temperature, and MOSFET rDS(ON)-based overcurrent protection - designed for VRM8.5-compliant microprocessor power delivery.
For engineers reviewing the HIP6004ECVZ datasheet, HIP6004ECVZ pinout, HIP6004ECVZ application, or HIP6004ECVZ equivalent, key selection considerations include its 200kHz free-running oscillator (adjustable 50kHz–1MHz), 15MHz gain-bandwidth error amplifier, 0–100% duty cycle capability, PGOOD window monitor (±10%), and TSSOP-20 Pb-free package compatibility with +5V/+12V bias supplies.
Technical Context
The HIP6004ECVZ implements voltage-mode PWM control using a high-bandwidth error amplifier (15MHz GBWP, 6V/µs slew rate) and a programmable triangle-wave oscillator. Its feedback loop uses COMP (error amp output) and FB (inverting input) to regulate output via DACOUT reference tracking.
Overcurrent protection operates without external sense resistors by comparing the voltage drop across the upper MOSFET's rDS(ON) against a current-source–set threshold (200µA into OCSET). Overvoltage protection triggers OVP pin sourcing (60mA) to drive an external SCR, while PGOOD asserts open-drain low when VSEN deviates >±10% from DACOUT.

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HIP6004ECBZ | Identical electrical specs; packaged in 20-lead SOIC (θJA = 65°C/W) instead of TSSOP | SOIC offers better thermal performance but larger PCB footprint; suitable for lower-density layouts with heatsinking | Select HIP6004ECBZ when thermal management prioritizes lower junction rise over board space |
| ISL6522CBZ | Same manufacturer, VRM8.5-compliant, but adds 6-bit DAC (32mV steps), dual-phase support, and enhanced transient response | Targeted at higher-performance CPU platforms requiring tighter voltage tolerance and multi-phase scalability | Choose ISL6522CBZ for next-generation designs needing extended VID resolution and phase interleaving |
Compared with HIP6004ECVZ, HIP6004ECBZ provides superior thermal dissipation in SOIC packaging but occupies more board area, while ISL6522CBZ delivers higher-resolution voltage control and multi-phase readiness - making it suitable for upgraded VRM architectures beyond VRM8.5 baseline.

FAQ
What is the recommended operating supply voltage for the HIP6004ECVZ?
The HIP6004ECVZ requires a +12V ±10% bias supply applied to the VCC pin (Pin 18). It is not rated for +5V-only operation - although the controller supports input sources of +5V or +12V for the main converter, the IC itself must be powered from +12V. Operating outside this range risks improper initialization or failure of internal references and gate drivers.
Does the HIP6004ECVZ require an external current-sense resistor?
No, the HIP6004ECVZ 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 (Pin 2) and an internal 200µA current source. This eliminates added power loss, board space, and cost associated with discrete sense resistors - a key design advantage confirmed in the FN4997 datasheet.
How is the output voltage programmed on the HIP6004ECVZ?
The HIP6004ECVZ uses a 5-bit digital-to-analog converter (DAC) with inputs VID25mV, VID0–VID3 (Pins 4–8) to program DACOUT from 1.05V to 1.825V in 25mV increments. Each combination corresponds to a specific voltage per Table 1 in the datasheet. Pins driven low (GND) or high (via pull-up) set the binary code; floating pins default high due to internal pull-ups. Voltage must be set before power-up - adjusting during operation may trigger PGOOD or OVP faults.
What is the function of the RT pin on the HIP6004ECVZ?
The RT pin (Pin 20) adjusts the HIP6004ECVZ oscillator frequency. With RT tied to GND, frequency increases above the nominal 200kHz (up to >1MHz); with RT pulled to VCC, frequency decreases (down to <50kHz). The pin maintains a 1.26V internal reference, and the relationship follows Fs ≈ 200kHz + 5×10⁶/RT(kΩ) (RT-to-GND) or Fs ≈ 200kHz − 4×10⁷/RT(kΩ) (RT-to-VCC), enabling precise EMI and efficiency tuning.
Can the HIP6004ECVZ be used in new designs today?
While the HIP6004ECVZ remains available through Aetrix Electronics for legacy support and obsolescence management, it is marked "no longer available or supported" by Renesas with HIP6004ECBZ recommended as replacement. New designs should evaluate modern alternatives like ISL6522CBZ or Renesas' newer ISL958xx series for improved integration, efficiency, and lifecycle assurance - though HIP6004ECVZ continues to function reliably in maintained VRM8.5 systems.
