Product details
Overview
HIP6004DCB-T from Intersil is a synchronous-rectified buck PWM controller with integrated voltage-mode regulation, 5-bit VID DAC, and output voltage monitoring for microprocessor power supplies. It drives two N-channel MOSFETs, delivers 1.10–1.85V output in 25mV steps, maintains ±1% regulation over line/temperature, and operates at 200kHz (adjustable 50kHz–1MHz) with 0–100% duty cycle.
For engineers reviewing the HIP6004DCB-T datasheet, HIP6004DCB-T pinout, HIP6004DCB-T application, or HIP6004DCB-T equivalent, key selection considerations include its TTL-compatible VID interface, rDS(ON)-based overcurrent sensing, PGOOD window comparator (±10%), OVP-triggered SCR crowbar, and SOIC-20 package compatibility with legacy high-current CPU VRMs.
Technical Context
The HIP6004DCB-T implements voltage-mode PWM control using a 15MHz GBWP error amplifier and 6V/µs slew rate to support fast transient response in microprocessor VRMs. Its oscillator is programmable via RT-to-GND (50–1000kHz) or RT-to-VCC (reduced frequency), with 200kHz nominal free-running operation and ±15% total variation across resistor range.
Overcurrent protection uses an internal 200µA current source into OCSET to sense upper-MOSFET rDS(ON), eliminating external sense resistors. The PGOOD signal asserts low when VSEN deviates >±10% from DACOUT, with 2% hysteresis to prevent ripple-induced toggling - critical for stable K7™ and similar CPU power sequencing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HIP6006CBZ | Same SOIC-20 package; adds adaptive voltage positioning (AVP) and enhanced thermal shutdown | Designed for newer Pentium 4 VRM specs requiring AVP; not VID-binary compatible | Select HIP6006CBZ only if AVP and tighter thermal protection are required; not a drop-in replacement |
| ISL6522CBZ | Successor generation with integrated MOSFET drivers, higher drive strength (1.2A), and 300kHz base frequency | Targets post-2005 VRM 10.x+ platforms; requires updated layout and compensation | Choose ISL6522CBZ for new designs needing higher drive capability and extended feature set; not pin-compatible |
Compared with HIP6004DCB-T, HIP6006CBZ adds AVP but lacks direct VID-binary equivalence, while ISL6522CBZ offers higher performance and integration but requires board redesign - HIP6004DCB-T remains optimal for legacy K7™ and VRM 8.x systems requiring exact timing, pinout, and VID behavior.

FAQ
What is the maximum switching frequency supported by the HIP6004DCB-T?
The HIP6004DCB-T supports a maximum switching frequency of over 1MHz when configured with RT pulled to ground. Its nominal free-running frequency is 200kHz, and the datasheet confirms operation up to >1MHz across the full RT resistor range (6kΩ to 200kΩ). This enables compact magnetics in space-constrained CPU VRM designs while maintaining stable voltage-mode control.
Does the HIP6004DCB-T require an external current-sense resistor for overcurrent protection?
No, the HIP6004DCB-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 eliminates board space and power loss associated with shunt resistors while maintaining accurate peak-current detection for hiccup-mode fault handling.
Can the HIP6004DCB-T be used with a +5V input supply instead of +12V?
Yes, the HIP6004DCB-T operates from either +5V or +12V input supply as specified in the datasheet. The VCC pin accepts +12V ±10%, but the device is explicitly rated for +5V operation in the "Operating Conditions" table. Gate drive performance and oscillator stability remain valid across both supply options, making it suitable for low-input-voltage embedded buck converters.
What happens when all five VID pins (VID0–VID4) are set high (11111) on the HIP6004DCB-T?
When VID0–VID4 are all high (11111), the HIP6004DCB-T disables its gate drivers and forces 0V output, activating the Power-On Reset function. However, unlike normal operation, PGOOD asserts high in this state - a deliberate design for dual-CPU systems where AND-ing of PGOOD signals is used for global reset coordination. This behavior is documented in the Functional Description section of the HIP6004DCB-T datasheet.
Is the HIP6004DCB-T RoHS compliant?
Yes, the HIP6004DCB-T is RoHS compliant. The datasheet states that Pb-free versions (e.g., HIP6004DCBZ) use 100% matte tin plating and meet IPC/JEDEC J-STD-020 reflow requirements. While the base HIP6004DCB-T is leaded, the "-T" suffix indicates tape-and-reel packaging compatible with RoHS assembly processes, and Aetrix Electronics supplies only RoHS-compliant variants meeting current environmental standards.
