Renesas HIP6004BCVZA

Overview

HIP6004BCVZA from Intersil is a synchronous-rectified buck PWM controller IC designed to drive two N-channel MOSFETs in high-performance microprocessor power supplies. It delivers precise output voltage regulation (±1% over line/temperature), supports 1.3V–3.5V DAC-programmable output via five VID pins, and integrates overvoltage/overcurrent protection using MOSFET r_DS(ON) sensing - eliminating external current-sense resistors. It targets Pentium®, Pentium Pro®, and PowerPC™ CPU core voltage regulation.

For engineers reviewing the HIP6004BCVZA datasheet, HIP6004BCVZA pinout, HIP6004BCVZA application, or HIP6004BCVZA equivalent, key selection criteria include its 200kHz free-running oscillator (adjustable 50kHz–1MHz), 15MHz error amplifier gain-bandwidth, 0%–100% duty cycle capability, TTL-compatible VID interface, and TSSOP-20 Pb-free RoHS-compliant package.

Technical Context

The HIP6004BCVZA implements voltage-mode PWM control with a single feedback loop, using an internal 200kHz triangle-wave oscillator and a high-speed error amplifier (15MHz GBW, 6V/µs slew rate) to achieve fast transient response. Its DAC-based reference (VID0–VID4) sets both output voltage and PGOOD/OVP thresholds simultaneously.

Overcurrent protection operates by comparing the voltage drop across the upper MOSFET's r_DS(ON) against a resistor-programmed threshold derived from a 200µA internal current source at OCSET. Overvoltage protection triggers an open-drain OVP signal to drive an external SCR and inhibits PWM operation when VSEN exceeds 115% of DACOUT.

Manufacturer

Intersil Corporation was a U.S.-based semiconductor company specializing in precision analog, power management, and interface ICs before its acquisition by Renesas Electronics in 2017.

The HIP6004B product line was developed specifically for single-phase, synchronous-buck CPU core voltage regulation in late-1990s/early-2000s microprocessor platforms, emphasizing VID compatibility, tight regulation, and MOSFET-integrated protection.

FAQ

What is the operating temperature range for the HIP6004BCVZA?

The HIP6004BCVZA is specified for an ambient temperature range of 0°C to +70°C. This rating applies to the TSSOP-20 package variant and is validated per the Absolute Maximum Ratings table in the FN4567 datasheet. Thermal performance is supported by θ_JA = 85°C/W for the TSSOP package, and junction temperature must remain below 150°C under all operating conditions. Derating is required above 70°C ambient.

Does the HIP6004BCVZA require an external current-sense resistor?

No, the HIP6004BCVZA does not require an external current-sense resistor. It 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, and the controller compares this to the MOSFET's on-state voltage drop to trigger hiccup-mode protection - a key cost and efficiency advantage of the HIP6004BCVZA.

Can the HIP6004BCVZA operate with a +5V input supply?

Yes, the HIP6004BCVZA supports operation from either +5V or +12V bias supply at the VCC pin, as explicitly stated in the datasheet Features section and Recommended Operating Conditions. The VCC supply must be within ±10% of nominal (i.e., 4.5–5.5V or 10.8–13.2V), and the internal circuitry - including gate drivers and error amplifier - is fully functional across both ranges. However, +12V is recommended for higher gate drive strength and improved noise immunity.

What is the function of the '11111' VID code on the HIP6004BCVZA?

The '11111' VID code (all five VID pins high) disables the HIP6004BCVZA gate drivers and forces 0V output, activating the Power-On Reset (POR) function. Unlike other VID codes, this combination causes the PGOOD pin to assert a high level instead of going low - a deliberate design feature enabling AND-ing of PGOOD signals in dual-CPU systems. This behavior is documented in the Functional Description section of the FN4567 datasheet and is intrinsic to the HIP6004BCVZA's logic architecture.

Is the HIP6004BCVZA pin-compatible with the HIP6004BCB and HIP6004BCR variants?

Yes, the HIP6004BCVZA (TSSOP-20) shares identical pin numbering, pin functions, and electrical specifications with the HIP6004BCB (SOIC-20) and HIP6004BCR (QFN-20) variants. All three packages implement the same die and pinout mapping per the "Pinouts" section of FN4567. Mechanical differences exist (footprint, thermal pad, height), but no signal-level or timing differences affect interoperability - making them direct drop-in replacements at the schematic and layout level.
