Product details
Overview
HIP6006CBZ-T from Intersil is a synchronous-rectified buck PWM controller IC designed to drive two N-channel MOSFETs in high-efficiency DC-DC converters for microprocessor power delivery. It delivers ±1% output voltage regulation down to 1.27V, supports 50kHz–1MHz programmable switching frequency, and implements rDS(ON)-based over-current protection without external sense resistors - used in Pentium® and PowerPC™ CPU core supplies.
For engineers reviewing the HIP6006CBZ-T datasheet, HIP6006CBZ-T pinout, HIP6006CBZ-T application, or HIP6006CBZ-T equivalent, key selection considerations include its voltage-mode control architecture, 15MHz error amplifier gain-bandwidth, 0–100% duty cycle range, SOIC-14 Pb-free package, and compatibility with +5V/+12V bias inputs for microprocessor VRM designs.
Technical Context
The HIP6006CBZ-T implements a single-loop voltage-mode PWM control architecture with an internal 1.27V reference and a 200kHz free-running oscillator adjustable via external RT resistor. Its error amplifier provides 15MHz gain-bandwidth and 6V/μs slew rate to support fast transient response in low-voltage, high-current CPU power rails.
Over-current protection uses the upper MOSFET's rDS(ON) as a current-sense element, referenced against an internal 200μA OCSET current source and external ROCSET resistor - eliminating discrete sense resistors while enabling hiccup-mode fault recovery. Soft-start is controlled by a 10μA internal current source charging an external SS capacitor to 4V.
Key Specifications

Pinout & Package
HIP6006CBZ-T is housed in a 14-lead SOIC package (JEDEC MS-012, package drawing M14.15), Pb-free and RoHS-compliant, with standard 1.27mm pitch and 8.65mm × 3.90mm body dimensions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RT (1) | Oscillator frequency programming | Resistor-to-GND or VCC sets switching frequency from 50kHz to >1MHz; enables layout-driven optimization of inductor/capacitor sizing. |
| OCSET (2) | Over-current trip reference | Connects to upper MOSFET drain; internal 200μA current source + external ROCSET resistor defines IPEAK trip threshold using rDS(ON). |
| SS (3) | Soft-start timing control | External capacitor charged by 10μA current source to 4V - controls ramp-up of output voltage and prevents inrush current damage. |
| COMP (4) | Error amplifier output | Drives compensation network; clamped during soft-start to limit initial duty cycle and ensure controlled startup. |
| FB (5) | Error amplifier inverting input | Connects to voltage divider from output - closes feedback loop for precision regulation at 1.27V reference. |
| EN (6) | Enable/disable control | Open-collector input; pulled below 1V to inhibit PWM and discharge SS capacitor - supports sequencing with other system rails. |
| GND (7) | Signal ground reference | Reference point for all analog circuitry; must be isolated from PGND to avoid noise coupling into error amplifier. |
| PHASE (8) | High-side switch node monitor | Connected to upper MOSFET source; provides return path for UGATE drive and voltage reference for OC detection. |
| UGATE (9) | Upper MOSFET gate driver output | Sources/sinks ≥350mA peak - directly drives standard N-channel MOSFET gates without external buffers. |
| BOOT (10) | Bootstrap supply for UGATE | Provides floating bias for high-side driver; requires external bootstrap diode and capacitor (CBOOT) for operation above VCC. |
| PGND (11) | Power ground return | Low-impedance return for lower MOSFET source and output inductor - must be tied to power plane, separate from signal GND. |
| LGATE (12) | Lower MOSFET gate driver output | Sources/sinks ≥300mA peak - drives synchronous rectifier with minimal dead-time distortion. |
| PVCC (13) | Lower gate driver bias supply | Accepts dedicated 5V–12V supply - decouples lower gate drive from main VCC, improving noise immunity and drive strength. |
| VCC (14) | Main IC bias supply | +12V ±10% input - powers internal logic, oscillators, and gate drivers; shutdown current <100μA when EN = 0V. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck PWM controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HIP6004CBZ-T | Lower gate drive strength (UGATE sink: 300mA vs. 500mA); no PVCC pin - lower MOSFET drive supplied from VCC. | Targeted at ≤15A applications; less suitable for high-current CPU cores requiring aggressive transient response. | Select HIP6004CBZ-T only when output current ≤12A and layout constraints preclude separate PVCC routing. |
| ISL6208IRZ-T | Integrated MOSFET drivers with higher peak current (1.2A UGATE); supports 300kHz–1.5MHz frequency range; includes adaptive dead-time control. | Designed for newer mobile CPU VRMs (e.g., Intel Core series); requires different compensation and layout due to enhanced features. | Choose ISL6208IRZ-T for next-gen designs needing higher drive capability, wider frequency range, and improved light-load efficiency - not drop-in compatible. |
Compared with HIP6004CBZ-T, HIP6006CBZ-T delivers higher upper gate drive current and independent PVCC biasing for improved lower-FET control, making it better suited for >15A microprocessor rails; versus ISL6208IRZ-T, it lacks adaptive dead-time and has narrower frequency range but offers simpler compensation and proven stability in legacy Pentium-class designs.

FAQ
What is the recommended input voltage range for HIP6006CBZ-T operation?
The HIP6006CBZ-T is specified for a VCC supply of +12V ±10%, meaning 10.8V to 13.2V. It can also operate from a +5V input when configured with direct VCC drive (per Figure 10), though this limits upper gate-to-source voltage. The IC does not regulate its own VCC - an external stable bias rail is required. Always verify VCC remains within absolute maximum rating (+15V) during transients.
How does HIP6006CBZ-T implement over-current protection without a sense resistor?
HIP6006CBZ-T uses the upper MOSFET's intrinsic rDS(ON) as a current-sensing element. An internal 200μA current source flows through an external ROCSET resistor connected to OCSET (Pin 2), developing a reference voltage. When the voltage drop across the upper MOSFET (measured between PHASE and OCSET) exceeds this reference, the controller triggers hiccup-mode soft-start restart. This eliminates external resistor losses and PCB area while maintaining accuracy dependent on MOSFET rDS(ON) specs.
Can HIP6006CBZ-T support output voltages below 1.27V?
No - the HIP6006CBZ-T has a fixed internal 1.27V reference voltage, and its feedback architecture is designed for regulation at or above this value. Output voltages lower than 1.27V cannot be achieved using the standard FB/REF configuration. For sub-1.27V applications, a different controller with adjustable reference or external reference injection would be required. The ±1% tolerance applies only within the 1.27V–3.3V operating range confirmed in the datasheet.
What is the function of the PVCC pin on HIP6006CBZ-T, and how should it be connected?
PVCC (Pin 13) supplies bias power exclusively to the lower gate driver (LGATE). It must be connected to a clean, low-impedance 5V or 12V source - separate from VCC - to maximize LGATE drive strength and minimize noise coupling into the error amplifier. Typical use connects PVCC to the same 12V rail as VCC, but with dedicated local decoupling (e.g., 1μF ceramic + 10μF tantalum). Using PVCC improves lower-FET turn-on speed and reduces shoot-through risk during dead-time transitions.
Is HIP6006CBZ-T pin-compatible with HIP6006CB-T or HIP6006CV-T?
Yes - HIP6006CBZ-T shares identical pinout and electrical specifications with HIP6006CB-T (standard SOIC) and HIP6006CV-T (TSSOP), differing only in Pb-free finish (CBZ/CVZ) and tape-and-reel packaging (–T suffix). All variants use the same M14.15 (SOIC) or M14.173 (TSSOP) package drawings and are functionally interchangeable in layout. No PCB changes are required when substituting HIP6006CBZ-T for HIP6006CB-T in existing designs.
