Product details
Overview
HIP6012CV 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% tolerance), 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®/PowerPC™ applications.
For engineers reviewing the HIP6012CV datasheet, HIP6012CV pinout, HIP6012CV application, or HIP6012CV equivalent, key selection considerations include its voltage-mode control architecture, rDS(ON)-based overcurrent protection, 15MHz gain-bandwidth error amplifier, TSSOP-14 package thermal performance (θJA = 95°C/W), and compatibility with +5V/+12V bias inputs.
Technical Context
The HIP6012CV implements voltage-mode PWM control using a 200kHz free-running oscillator adjustable via external RT resistor, with ramp amplitude fixed at 1.9VP-P. Its error amplifier provides 88dB DC gain, 15MHz gain-bandwidth product, and 6V/μs slew rate to support fast transient response in microprocessor VRMs.
Overcurrent protection operates by comparing the voltage drop across the upper MOSFET's rDS(ON) against a reference set by an internal 200μA current source and external ROCSET resistor-eliminating need for sense resistors. Soft-start is implemented via 10μA internal current source charging external CSS capacitor to 4V.

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 |
|---|---|---|---|
| HIP6006CB | Same pinout, identical functional block diagram, but ±2% reference tolerance vs. HIP6012CV's ±1.5% | Valid for legacy Pentium designs; lacks extended soft-start control and tighter regulation needed for newer Alpha cores | Select HIP6012CV when ±1.5% output accuracy and enhanced transient response are required |
| ISL6223AIRZ | Integrated MOSFET drivers with higher peak current (1.2A), but requires external overcurrent sensing resistor | Targeted at mobile CPU VRMs with dynamic VID interface; no native support for fixed 1.27V reference operation | Choose ISL6223AIRZ only if VID programming and higher gate drive current outweigh loss of rDS(ON) sensing simplicity |
Compared with HIP6006CB and ISL6223AIRZ, the HIP6012CV uniquely combines tight ±1.5% regulation, rDS(ON)-based overcurrent protection, and TSSOP-14 thermal performance-making it optimal for fixed-output, high-accuracy microprocessor core supplies where BOM count and layout simplicity are critical.

FAQ
What is the recommended input voltage range for HIP6012CV operation?
The HIP6012CV is specified for VCC supply voltage of +12V ±10%, meaning 10.8V to 13.2V nominal operation. It also supports +5V input configurations using the direct VCC drive option shown in Figure 10 of the datasheet. The PVCC pin accepts 5V–12V for lower gate driver bias. Operation outside these ranges risks violating absolute maximum ratings and may cause malfunction or permanent damage to the HIP6012CV.
How does HIP6012CV implement overcurrent protection without a sense resistor?
The HIP6012CV uses the upper MOSFET's intrinsic rDS(ON) as a current-sense element. An internal 200μA current source flows through an external ROCSET resistor to generate a reference voltage. When the voltage drop across the upper MOSFET (IPEAK × rDS(ON)) exceeds this reference, the HIP6012CV triggers hiccup-mode soft-start restart. This eliminates external sense resistors while maintaining accuracy across temperature when ROCSET is selected using max rDS(ON) and min IOCSET values.
What is the function of the PHASE pin on HIP6012CV?
The PHASE pin on HIP6012CV serves three critical functions: (1) it connects to the source terminal of the upper MOSFET to monitor its rDS(ON) voltage for overcurrent detection; (2) it provides the return current path for the UGATE driver; and (3) it acts as the switching node reference for the bootstrap capacitor (CBOOT). Proper low-inductance routing of PHASE is essential to avoid noise coupling into the overcurrent comparator and ensure stable UGATE drive in the HIP6012CV.
Can HIP6012CV be used with logic-level MOSFETs?
Yes, HIP6012CV can drive logic-level MOSFETs, but with constraints: for the upper MOSFET (Q1), the device's absolute gate-source voltage rating must exceed VCC minus the boot diode drop (typically ~11.3V with 12V VCC); for the lower MOSFET (Q2), the rating must exceed the PVCC supply voltage. Standard-gate MOSFETs are preferred for robustness, but logic-level devices may be used in +5V-input systems where gate drive margins are sufficient-always verify with HIP6012CV's actual UGATE/LGATE output swing and MOSFET datasheet limits.
What is the purpose of the separate PVCC pin on HIP6012CV?
The PVCC pin on HIP6012CV supplies dedicated bias power to the lower gate driver (LGATE), isolating it from the main VCC rail that powers internal logic, oscillators, and reference circuits. This separation prevents high di/dt switching currents from LGATE from injecting noise into sensitive analog blocks like the error amplifier and reference, thereby improving loop stability and reducing output voltage ripple. PVCC should be decoupled with a local 1μF ceramic capacitor close to the HIP6012CV package.
