Product details
Overview
HIP6012CBZ 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 dynamic load response in Pentium® and PowerPC™ applications.
For engineers reviewing the HIP6012CBZ datasheet, HIP6012CBZ pinout, HIP6012CBZ application, or HIP6012CBZ equivalent, this page provides verified functional context, validated pin-level circuit roles, confirmed overcurrent protection using rDS(ON) sensing, and real-world design implications of its 15MHz error amplifier GBW and 6V/µs slew rate.
Technical Context
The HIP6012CBZ implements voltage-mode PWM control with a 200kHz free-running oscillator adjustable via external RT resistor, enabling stable constant-frequency operation across 50kHz–1MHz. Its error amplifier features 15MHz gain-bandwidth and 6V/µs slew rate to support fast transient response in low-voltage, high-current DC-DC converters.
Overcurrent protection operates without external sense resistors by monitoring voltage drop across the upper MOSFET's rDS(ON) using an internal 200µA current source at OCSET and comparing it against PHASE node voltage. Fault detection triggers hiccup-mode soft-start cycling to limit power dissipation during sustained overload.

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 | Same 14-pin SOIC package and pinout; fixed 200kHz oscillator (non-programmable); ±2.0% reference tolerance vs. HIP6012CBZ's ±1.5%. | Lacks RT programmability and tighter reference; suitable only where fixed frequency suffices and looser regulation is acceptable. | Select HIP6006CBZ only when oscillator flexibility and reference precision are not required; not drop-in for HIP6012CBZ designs relying on RT or tight VREF. |
| ISL6223CRZ | Intersil successor with integrated MOSFET drivers, 300kHz–1.5MHz programmability, and ±0.8% reference; requires different compensation and layout due to higher integration. | Targets newer CPU VRMs with tighter transient specs; includes additional features like remote sensing and adaptive voltage positioning. | Choose ISL6223CRZ for next-generation designs needing enhanced accuracy and integration; redesign required due to non-pin-compatible layout and control architecture. |
Compared with HIP6006CBZ, HIP6012CBZ offers superior reference accuracy and oscillator flexibility but shares identical package and basic control architecture; compared with ISL6223CRZ, it provides simpler implementation and legacy compatibility at the cost of modern VRM feature set and tighter tolerances.

FAQ
What is the operating temperature range for the HIP6012CBZ?
The HIP6012CBZ is specified for an ambient temperature range of 0°C to 70°C, with a junction temperature limit of 125°C and maximum storage temperature of –65°C to 150°C. Its thermal resistance (θJA) is 85°C/W in the SOIC package, enabling reliable operation in convection-cooled computing and industrial environments when properly heatsinked or airflow-managed.
How does the HIP6012CBZ implement overcurrent protection without a sense resistor?
The HIP6012CBZ uses the upper MOSFET's rDS(ON) as the current-sensing element. An internal 200µA current source at the OCSET pin develops a voltage across an external ROCSET resistor; when the voltage drop across the upper MOSFET (measured at PHASE relative to VIN) exceeds that voltage, the controller initiates hiccup-mode soft-start cycling. This eliminates external sense resistors while maintaining accuracy tied to MOSFET datasheet rDS(ON) specs.
Can the HIP6012CBZ operate with a +5V input supply instead of +12V?
Yes - the HIP6012CBZ supports operation from either +5V or +12V input, as stated in the datasheet. However, VCC must be supplied at +12V ±10% for proper internal biasing; the +5V or +12V designation refers to the main converter input (VIN), not the IC's VCC rail. The PVCC pin may be supplied from +5V for the lower gate driver if system constraints require it, but VCC must remain at 12V.
What is the purpose of the separate PVCC pin on the HIP6012CBZ?
The PVCC pin provides an isolated bias supply for the lower gate driver (LGATE), decoupling it from the main VCC rail. This separation reduces noise coupling from high-current switching events into the lower driver stage, improving gate drive integrity and minimizing shoot-through risk. It also allows independent optimization of PVCC filtering, enhancing reliability in noisy power-system environments where the HIP6012CBZ is deployed.
Does the HIP6012CBZ support both bootstrap and direct-drive configurations for the upper MOSFET?
Yes - the HIP6012CBZ supports both configurations. For bootstrap drive, BOOT connects to a capacitor referenced to PHASE, enabling standard N-channel high-side FETs with 12V gate drive. For direct drive (e.g., in +5V-input systems), UGATE can be driven directly from VCC, provided the upper MOSFET's absolute gate-source rating exceeds VCC minus VIN. Figure 9 and Figure 10 in FN4324 confirm both topologies are validated for HIP6012CBZ.
