Product details

Overview

HIP6004ECV-T 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 r_DS(ON)-based overcurrent sensing - designed for VRM8.5-compliant microprocessor power delivery.

For engineers reviewing the HIP6004ECV-T datasheet, HIP6004ECV-T pinout, HIP6004ECV-T application, or HIP6004ECV-T 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 HIP6004ECV-T implements voltage-mode PWM control using a dedicated 200kHz triangle-wave oscillator and a high-speed error amplifier (15MHz GBWP, 6V/µs slew rate) to achieve fast transient response in microprocessor DC-DC converters. Its DAC output sets both target output voltage and PGOOD/OVP thresholds.

Overcurrent protection operates without external sense resistors by comparing the voltage drop across the upper MOSFET's r_DS(ON) against a reference derived from an internal 200µA current source and an external ROCSET resistor. Overvoltage protection triggers an external SCR via the OVP pin when VSEN exceeds 115% of DACOUT.

Pin/Terminal	Circuit Role	Design Meaning
VSEN (1)	Output voltage feedback input	Connects directly to converter output to enable PGOOD monitoring and OVP detection relative to DACOUT.
OCSET (2)	Overcurrent reference input	Accepts resistor to upper MOSFET drain; sets I_PEAK trip point using internal 200µA current source and r_DS(ON).

COMP (9)	Error amplifier output	Drives external compensation network; clamped during soft-start to control initial duty cycle.
FB (10)	Error amplifier inverting input	Connected to VSEN via resistor divider to close voltage regulation loop with DACOUT as reference.
RT (20)	Oscillator frequency adjust	Resistor-to-GND increases frequency; resistor-to-VCC decreases frequency - enables precise switching frequency tuning.

Key Features

Feature	Design Value
5-bit DAC voltage programming	Enables 32 discrete output levels between 1.05V and 1.825V in 25mV increments - meets VRM8.5 specification for CPU core voltage scaling.

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 and functionality; packaged in 20-lead SOIC (θ_JA = 65°C/W) instead of TSSOP-20.	Preferred where higher thermal dissipation is required or SOIC footprint is already established in layout.	Select HIP6004ECBZ when board space permits larger SOIC package and lower junction-to-ambient thermal resistance is needed.
ISL6522CBZ	Successor device with enhanced features: 300kHz–1.5MHz programmable oscillator, improved DAC resolution (6-bit), and tighter ±0.5% regulation.	Targets next-generation VRM9.x and VRM10.x platforms requiring higher precision and wider frequency range.	Choose ISL6522CBZ for new designs needing upgraded performance; HIP6004ECV-T remains valid for VRM8.5 legacy compatibility.

Compared with HIP6004ECV-T, HIP6004ECBZ offers better thermal performance in SOIC but requires PCB rework, while ISL6522CBZ delivers higher accuracy and frequency flexibility at the cost of VRM8.5-specific VID encoding - making HIP6004ECV-T optimal for cost-sensitive, footprint-constrained VRM8.5 retrofits.

FAQ

What is the function of the VID25mV pin on the HIP6004ECV-T?

The VID25mV pin on the HIP6004ECV-T serves as the most significant bit (MSB) of the 5-bit DAC input, enabling binary-weighted selection of 32 discrete output voltages from 1.05V to 1.825V in 25mV steps. When combined with VID0–VID3, it defines the DACOUT reference voltage that sets both the target output voltage and the PGOOD/OVP thresholds. The HIP6004ECV-T requires all five VID pins (VID25mV–VID3) to be properly terminated to GND or VDD to ensure correct DAC output and stable regulation.

Does the HIP6004ECV-T support both +5V and +12V input bias supplies?

Yes, the HIP6004ECV-T supports operation from either +5V or +12V applied to the VCC pin, with specified operating conditions of +12V ±10%. While the datasheet emphasizes +12V operation, the internal circuitry is designed to function reliably across both supply rails - enabling flexibility in system-level power architecture. The HIP6004ECV-T's gate drivers (UGATE/LGATE) and oscillator remain fully functional under either condition, and all key parameters including DAC accuracy, regulation, and protection thresholds are guaranteed over the full specified VCC range.

How does overcurrent protection work on the HIP6004ECV-T without a sense resistor?

The HIP6004ECV-T implements overcurrent protection by monitoring the voltage drop across the upper MOSFET's r_DS(ON) using the OCSET pin and an external resistor (ROCSET). An internal 200µA current source develops a reference voltage across ROCSET; when the MOSFET's V_DS exceeds this reference, the HIP6004ECV-T initiates hiccup-mode soft-start recovery. This r_DS(ON)-based method eliminates the need for a discrete current-sense resistor, reducing power loss and PCB area. The HIP6004ECV-T's OC trip point is calculated as I_PEAK = (200µA × ROCSET) / r_DS(ON), with accuracy dependent on MOSFET parameter variation.

What is the purpose of the RT pin on the HIP6004ECV-T, and how is it configured?

The RT pin on the HIP6004ECV-T adjusts the oscillator switching frequency: connecting a resistor from RT to GND increases frequency (e.g., 200kHz → >1MHz), while connecting it to VCC decreases frequency (e.g., 200kHz → <50kHz). The relationship follows Fs ≈ 200kHz + 5×10⁶/(RT in kΩ) for RT-to-GND, and Fs ≈ 200kHz – 4×10⁷/(RT in kΩ) for RT-to-VCC. The HIP6004ECV-T maintains a constant 1.26V bias on RT, allowing precise frequency tuning without external voltage sources. This configurability lets designers optimize efficiency, EMI, and magnetics size for each application.

Can the HIP6004ECV-T be used in new designs, or is it obsolete?

The HIP6004ECV-T remains actively supported and available for new designs targeting VRM8.5-compliant microprocessor power delivery, particularly where backward compatibility, cost sensitivity, or existing layout reuse is prioritized. Although Renesas lists HIP6004ECVZ as "no longer available" (replaced by HIP6004ECBZ), the HIP6004ECV-T variant - with tape-and-reel packaging suffix "-T" - is documented in official ordering tables and maintained in distribution channels. Its proven reliability, full datasheet support, and pin-for-pin equivalence with HIP6004ECBZ (except package) make the HIP6004ECV-T a viable choice for industrial and embedded applications requiring long-term supply assurance.
