Product details
Overview
HIP6012CBZ-T 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 regulation (±1.5% over line/temperature), supports 50kHz–1MHz programmable switching frequency, and enables 0%–100% duty cycle operation for low-voltage DC-DC conversion down to 1.27V in Pentium® and PowerPC™ applications.
For engineers reviewing the HIP6012CBZ-T datasheet, HIP6012CBZ-T pinout, HIP6012CBZ-T application, or HIP6012CBZ-T equivalent, key selection considerations include its voltage-mode control architecture, rDS(ON)-based overcurrent protection, 15MHz error amplifier GBW, bootstrap gate drive capability, and SOIC-14 Pb-free RoHS-compliant packaging.
Technical Context
The HIP6012CBZ-T implements a fixed-frequency, voltage-mode PWM control loop with 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 microprocessor VRMs.
Overcurrent protection operates without a sense resistor by monitoring the upper MOSFET's rDS(ON) voltage drop via OCSET pin and an internal 200μA current source. Soft-start is controlled by an external capacitor on SS pin charged/discharged by a 10μA internal current source.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reference Voltage | 1.27V ±1.5% - Enables stable output regulation down to 1.27V with minimal drift across temperature and input line variation. |
| Oscillator Frequency Range | 50kHz to >1MHz - Programmable via RT resistor; supports optimized efficiency vs. size trade-offs in compact VRM designs. |
| Error Amplifier GBW | 15MHz - Delivers high closed-loop bandwidth for rapid load transient recovery in microprocessor supply applications. |
| Duty Cycle Range | 0% to 100% - Allows full control of buck converter output, including startup into pre-biased loads and deep dropout operation. |
| Gate Drive Capability | UGATE: 500mA source / 5.5Ω sink; LGATE: 450mA source / 3.5Ω sink - Sufficient to drive standard N-channel MOSFETs with low gate charge at up to 1MHz. |
| OCSET Current Source | 200μA (typ) - Sets overcurrent trip threshold using upper MOSFET rDS(ON); eliminates need for external sense resistor and associated power loss. |
| Supply Voltage Range | VCC = +12V ±10% - Designed for single-rail bias from main input rail; no auxiliary supply required for core logic. |
Pinout & Package
Package: 14-lead SOIC (M14.15), Pb-free/RoHS-compliant, rated for 0°C to +70°C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RT (1) | Oscillator frequency programming | Resistor-to-GND or -VCC sets switching frequency from 50kHz to >1MHz per documented equations. |
| OCSET (2) | Overcurrent trip reference | Internal 200μA current source develops voltage across ROCSET; compared to PHASE voltage to detect rDS(ON)-based overload. |
| SS (3) | Soft-start timing control | 10μA internal current charges external capacitor to 4V; clamps COMP and reference during startup for controlled VOUT ramp. |
| COMP (4) | Error amplifier output | Drives PWM comparator; used with external compensation network (R/C) to stabilize voltage-mode feedback loop. |
| FB (5) | Error amplifier inverting input | Connects to resistor divider from VOUT; compares actual output to 1.27V internal reference for regulation. |
| EN (6) | Enable/disable control | Open-collector input; pulled below 1V disables PWM, discharges SS, and holds UGATE/LGATE low. |
| GND (7) | Signal ground reference | Common return for all analog and logic circuitry; must be low-impedance connection to minimize noise coupling. |
| PHASE (8) | High-side switch node monitor | Connected to source of upper MOSFET; provides return path for UGATE drive and rDS(ON) voltage sensing for OC protection. |
| UGATE (9) | Upper MOSFET gate driver output | Sources/sinks up to 500mA/5.5Ω; requires external bootstrap circuit (BOOT/PHASE) for high-side N-MOSFET drive. |
| BOOT (10) | Bootstrap supply for UGATE | Provides floating bias for upper gate driver; charged via external diode/capacitor during LGATE conduction phase. |
| PGND (11) | Power ground return | Low-inductance return path for lower MOSFET source current; must be separated from signal GND to avoid noise injection. |
| LGATE (12) | Lower MOSFET gate driver output | Sources/sinks up to 450mA/3.5Ω; directly drives synchronous rectifier MOSFET with minimal external components. |
| PVCC (13) | Lower gate driver supply | Bias supply for LGATE driver; may be tied to VCC or derived separately for optimal drive strength and noise isolation. |
| VCC (14) | Main IC supply input | +12V ±10% bias input powering internal logic, oscillators, and gate drivers; also serves as POR monitoring point. |

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 |
|---|---|---|---|
| HIP6006CBZ-T | Same pinout, identical SOIC-14 package, but uses current-mode control and lacks 0%–100% duty cycle; reference tolerance ±2.0% vs. ±1.5%. | Less suitable for pre-biased startup or ultra-low-VOUT applications; lower transient bandwidth due to current-mode loop limitations. | Select HIP6012CBZ-T when voltage-mode control, wider duty range, or tighter reference accuracy is required. |

FAQ
What is the operating temperature range for the HIP6012CBZ-T?
The HIP6012CBZ-T is specified for an ambient operating temperature range of 0°C to +70°C. Its junction temperature can reach up to +125°C under normal operation, with a maximum allowable junction temperature of +150°C. The device incorporates Power-On Reset (POR) circuitry that monitors VCC and OCSET voltages to ensure safe initialization within this range. Thermal resistance θJA is 85°C/W for the SOIC package, enabling reliable operation in typical PCB layouts with moderate airflow.
Does the HIP6012CBZ-T require an external current-sense resistor for overcurrent protection?
No, the HIP6012CBZ-T does not require an external current-sense resistor. It implements rDS(ON)-based overcurrent protection by using an internal 200μA current source connected to the OCSET pin and comparing the resulting voltage across an external ROCSET resistor to the voltage drop across the upper MOSFET's rDS(ON), measured at the PHASE pin. This method eliminates sense-resistor losses and reduces component count, making HIP6012CBZ-T particularly suitable for high-efficiency, high-current microprocessor VRMs.
Can the HIP6012CBZ-T support startup into a pre-biased output?
Yes, the HIP6012CBZ-T supports startup into a pre-biased output due to its 0% to 100% PWM duty cycle capability. During soft-start, the error amplifier output (COMP pin) and reference input are clamped to the rising SS pin voltage, allowing controlled ramping even when the output already holds voltage. This feature prevents reverse current flow and ensures monotonic VOUT rise, making HIP6012CBZ-T appropriate for systems with multiple power domains or hot-swap requirements.
What is the function of the BOOT and PHASE pins on the HIP6012CBZ-T?
The BOOT pin provides the floating bias supply for the upper gate driver (UGATE), generated via an external bootstrap circuit consisting of a diode and capacitor connected between VCC and PHASE. The PHASE pin connects to the source of the upper MOSFET and serves two roles: (1) it provides the return path for UGATE drive current, and (2) it enables rDS(ON)-based overcurrent sensing by referencing the OCSET voltage to the upper MOSFET's source potential. Together, BOOT and PHASE allow HIP6012CBZ-T to drive standard N-channel MOSFETs in high-side configuration without requiring a dedicated high-side supply.
Is the HIP6012CBZ-T RoHS-compliant and lead-free?
Yes, the HIP6012CBZ-T is RoHS-compliant and lead-free. The "Z" suffix in the part number explicitly denotes Intersil's Pb-free product variant, which uses 100% matte tin plate termination finish and Pb-free molding compounds/die attach materials. It meets or exceeds IPC/JEDEC J-STD-020 reflow profile requirements for Pb-free soldering and is compatible with both SnPb and Pb-free assembly processes, ensuring flexibility in manufacturing and long-term environmental compliance.
