Product details
Overview
HIP6004ECVZ-T from Intersil is a synchronous-rectified buck PWM controller with integrated voltage-mode regulation, 5-bit DAC-based output voltage programming (1.05–1.825V in 25mV steps), ±1% output regulation over line/temperature, and MOSFET rDS(ON)-based overcurrent sensing - designed for VRM8.5-compliant microprocessor power delivery.
For engineers reviewing the HIP6004ECVZ-T datasheet, HIP6004ECVZ-T pinout, HIP6004ECVZ-T application, or HIP6004ECVZ-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 comparator (±10%), and TSSOP-20 Pb-free package compatibility.
Technical Context
The HIP6004ECVZ-T implements voltage-mode PWM control using a high-bandwidth error amplifier (15MHz GBWP, 6V/µs slew rate) and a programmable triangle-wave oscillator. Its DAC output sets both target output voltage and PGOOD/OVP thresholds, enabling precise coordination of regulation and protection.
Overcurrent detection uses an internal 200µA current source at OCSET to bias a resistor against the upper MOSFET's rDS(ON), eliminating external sense resistors. Protection includes hiccup-mode soft-start restart on overcurrent, 115% overvoltage trip, and SCR-triggered crowbar via OVP pin.

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 | Same die, SOIC-20 package (θJA = 65°C/W); no longer supported per datasheet - recommended replacement is HIP6004ECBZ | Higher thermal performance in less dense layouts; not Pb-free compatible with same reflow profile as HIP6004ECVZ-T | Select only if SOIC footprint is fixed and Pb-free compliance is not required. |
| ISL6522CBZ | Successor device with enhanced 0.8–2.5V DAC range, 300kHz–1.5MHz oscillator, and improved thermal shutdown - also TSSOP-20 | Supports newer CPU VID standards and higher switching frequencies; requires updated compensation design | Preferred for new designs needing extended voltage range, higher frequency, and active thermal protection. |
Compared with HIP6004ECVZ-T, HIP6004ECBZ offers better thermal dissipation but lacks Pb-free qualification, while ISL6522CBZ extends functionality with wider DAC range and faster oscillator - making it suitable for next-generation VRM implementations where backward compatibility is not mandatory.

FAQ
What is the function of the VID25mV pin on the HIP6004ECVZ-T?
The VID25mV pin on the HIP6004ECVZ-T serves as the most significant bit (MSB) of the 5-bit digital-to-analog converter (DAC) that sets the target output voltage. Combined with VID0–VID3, it selects one of 32 discrete output voltages between 1.05V and 1.825V in 25mV increments. The HIP6004ECVZ-T uses this DACOUT voltage not only for regulation but also as the reference for PGOOD and OVP comparators - ensuring coordinated monitoring across all control and protection functions.
Can the HIP6004ECVZ-T operate with a +5V input supply?
Yes, the HIP6004ECVZ-T supports operation from either +5V or +12V input supplies as specified in the datasheet. Its VCC pin accepts +12V ±10%, and the OCSET pin monitors the input rail directly - enabling use in both 5V- and 12V-input synchronous buck configurations. However, gate drive strength (UGATE/LGATE) and bootstrap operation are optimized for 12V bias; at 5V, designers must verify MOSFET turn-on thresholds and ensure sufficient VGS margin for reliable switching in the HIP6004ECVZ-T application.
How does overcurrent protection work in the HIP6004ECVZ-T without a sense resistor?
The HIP6004ECVZ-T implements overcurrent protection by leveraging the upper MOSFET's intrinsic on-resistance (rDS(ON)). An internal 200µA current source at the OCSET pin develops a voltage across an external resistor (ROCSET), which is compared to the voltage drop across the MOSFET's rDS(ON) during conduction. When the latter exceeds the former, the HIP6004ECVZ-T initiates hiccup-mode soft-start restart. This method eliminates the need for a discrete current-sense resistor - reducing power loss, board space, and cost while maintaining accurate peak-current limiting calibrated to the actual FET's characteristics.
What is the purpose of the RT pin on the HIP6004ECVZ-T?
The RT pin on the HIP6004ECVZ-T controls the switching frequency of the internal oscillator. Connecting a resistor from RT to GND increases the nominal 200kHz frequency according to Fs ≈ 200kHz + 5×10⁶/(RT in kΩ); connecting it to VCC decreases frequency per Fs ≈ 200kHz – 4×10⁷/(RT in kΩ). This programmability allows designers to optimize the HIP6004ECVZ-T for specific trade-offs - such as smaller magnetics at higher frequencies or improved efficiency at lower frequencies - without changing the IC or compensation network.
Is the HIP6004ECVZ-T still in active production?
No - the HIP6004ECVZ-T is listed in the official datasheet (FN4997 Rev 3.00) as "no longer available or supported", with HIP6004ECBZ cited as the recommended replacement. While Aetrix Electronics maintains legacy supply channels for the HIP6004ECVZ-T to support existing designs and end-of-life transitions, new designs should consider the ISL6522CBZ or other Renesas-integrated VRM controllers offering extended features, active support, and full Pb-free compliance aligned with current manufacturing standards.
