Product details
Overview
HIP6006CBZ 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 1.27V internal reference, ±1% output voltage regulation over line and temperature, 0–100% duty cycle control, and MOSFET rDS(ON)-based over-current protection - enabling compact, efficient DC-DC conversion for Pentium® and PowerPC™ applications.
For engineers reviewing the HIP6006CBZ datasheet, HIP6006CBZ pinout, HIP6006CBZ application, or HIP6006CBZ equivalent, key selection considerations include its 200kHz programmable oscillator (50kHz–1MHz), 15MHz error amplifier gain-bandwidth, 6V/μs slew rate, SOIC-14 Pb-free package, and integrated soft-start with 10μA current source.
Technical Context
The HIP6006CBZ implements voltage-mode PWM control using a single feedback loop with an internal 1.27V reference and high-bandwidth error amplifier (15MHz GBW, 6V/μs slew rate) to achieve fast transient response in microprocessor VRMs. Its oscillator frequency is set via external RT resistor and supports both pull-up and pull-down configurations for wide-range tuning (50kHz–1MHz).
Over-current protection operates by comparing the voltage drop across the upper MOSFET's rDS(ON) against a reference generated by an internal 200μA OCSET current source and external ROCSET resistor - eliminating need for sense resistors. Fault detection triggers hiccup-mode soft-start recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reference Voltage | 1.27V ±1% - enables tight output regulation down to 1.27V without external DAC or trimming. |
| Oscillator Frequency Range | 50kHz to >1MHz - adjustable via RT resistor; default 200kHz free-running for optimal EMI/efficiency trade-off. |
| Error Amplifier GBW | 15MHz - supports high-loop bandwidth for sub-100ns load transient response in CPU core supplies. |
| Slew Rate | 6V/μs - ensures rapid error amplifier output recovery during large load steps. |
| OCSET Current Source | 200μA typical - sets over-current trip threshold with external ROCSET and MOSFET rDS(ON). |
| Soft-Start Current | 10μA - charges external CSS capacitor linearly to 4V, controlling ramp time and inrush current. |
| Supply Voltage Range | +12V ±10% - compatible with standard logic-level bias rails; VCC and PVCC support independent gate drive sourcing. |
Pinout & Package
HIP6006CBZ is housed in a 14-lead SOIC package (Pb-free, RoHS-compliant, pkg drawing M14.15), rated for 0°C to 70°C ambient operation and 125°C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RT (1) | Oscillator frequency adjust | Resistor-to-GND or resistor-to-VCC sets switching frequency from 50kHz to >1MHz per documented equations. |
| OCSET (2) | Over-current trip reference | Internal 200μA sink develops voltage across ROCSET; compared to PHASE–VIN drop to detect MOSFET conduction current. |
| SS (3) | Soft-start timing node | 10μA internal current source charges external capacitor to 4V, clamping COMP and reference during startup. |
| COMP (4) | Error amplifier output | Drives PWM comparator input; used with external compensation network (ZIN/ZFB) to stabilize voltage-mode loop. |
| FB (5) | Error amplifier inverting input | Connects to resistor divider from VOUT; compares actual output to 1.27V reference for regulation. |
| EN (6) | Enable control | Open-collector input; pulled low (<1V) disables UGATE/LGATE and discharges SS capacitor. |
| GND (7) | Signal ground reference | Common return for all analog and logic circuitry; separate from PGND to avoid noise coupling. |
| PHASE (8) | High-side switch node monitor | Connected to upper MOSFET source; provides return path for UGATE drive and rDS(ON) voltage sensing. |
| UGATE (9) | Upper MOSFET gate driver | Sources/sinks ≥350mA peak; requires bootstrap (BOOT–PHASE) or direct VCC drive depending on VIN. |
| BOOT (10) | Bootstrap supply for UGATE | Floats above PHASE; charged via external diode/capacitor to provide >10V gate drive for N-MOSFET. |
| PGND (11) | Power ground return | Low-impedance return for lower MOSFET source and high-current paths; must be separated from signal GND. |
| LGATE (12) | Lower MOSFET gate driver | Sources/sinks ≥300mA peak; driven from PVCC rail to optimize RDS(ON) and switching loss. |
| PVCC (13) | Lower gate driver supply | Accepts +5V or +12V; decoupled locally to minimize shoot-through risk and gate drive impedance. |
| VCC (14) | Main IC bias supply | +12V ±10% input powering internal logic, oscillator, and error amplifier; draws 5mA typical. |

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 | Lower oscillator frequency range (100–600kHz), no OCSET pin - uses external current-sense resistor. | Lacks rDS(ON) sensing; requires additional PCB area and power loss for sense resistor. | Select HIP6004CBZ only if fixed-frequency operation below 50kHz is required and MOSFET rDS(ON) variation is unacceptable for current sensing. |
| ISL6225CRZ | Integrated MOSFET drivers with higher peak current (1.2A), supports 3-phase operation, 300kHz–1.5MHz range. | Targets multi-phase CPU VRMs; not pin-compatible and requires different layout and compensation. | Choose ISL6225CRZ when scaling beyond 30A or requiring phase interleaving; HIP6006CBZ remains optimal for single-phase ≤25A designs. |
Compared with HIP6004CBZ and ISL6225CRZ, the HIP6006CBZ uniquely balances wide-frequency programmability, MOSFET-loss-free current sensing, and SOIC-14 simplicity - making it the preferred choice for cost-sensitive, single-phase microprocessor core supplies demanding ±1% regulation and hiccup-mode fault recovery.

FAQ
What is the operating temperature range for the HIP6006CBZ?
The HIP6006CBZ is specified for an ambient temperature range of 0°C to 70°C, with a maximum junction temperature of 125°C. Its thermal resistance θJA is 85°C/W in the SOIC-14 package, enabling reliable operation in microprocessor VRM environments with adequate airflow or heatsinking. The HIP6006CBZ datasheet confirms this rating applies specifically to the HIP6006CBZ variant.
Does the HIP6006CBZ require an external current-sense resistor?
No, the HIP6006CBZ does not require an external current-sense resistor. It implements over-current protection by monitoring the voltage drop across the upper MOSFET's rDS(ON) using the OCSET pin and an internal 200μA current source. This design eliminates sense resistor losses and reduces component count - a confirmed feature of the HIP6006CBZ per FN4306 Rev.3.00 datasheet.
What is the function of the BOOT and PHASE pins on the HIP6006CBZ?
The BOOT pin provides a floating bias voltage referenced to the PHASE pin, enabling full enhancement of the upper N-channel MOSFET gate. PHASE connects directly to the upper MOSFET source and serves as both the return path for UGATE drive and the sensing node for rDS(ON)-based over-current protection. These functions are explicitly defined for the HIP6006CBZ in the Functional Pin Description section of the official datasheet.
Can the HIP6006CBZ operate with a 5V input supply?
Yes, the HIP6006CBZ supports operation from either +5V or +12V input supplies, as stated in the datasheet Features section and Recommended Operating Conditions table. When using +5V, the upper gate drive configuration must be verified - direct VCC drive (Figure 10) is recommended for VIN ≤5V, while bootstrap operation (Figure 9) is used for higher inputs. This dual-supply capability is validated for the HIP6006CBZ.
What is the purpose of the SS (soft-start) pin on the HIP6006CBZ?
The SS pin on the HIP6006CBZ controls the soft-start interval via an external capacitor charged by an internal 10μA current source to 4V. During startup, the SS voltage clamps both the error amplifier output (COMP) and reference input, ensuring controlled output voltage ramp and limiting inrush current. This behavior is fully documented for the HIP6006CBZ in the Functional Description and Electrical Specifications sections of FN4306 Rev.3.00.
