Product details
Overview
HIP6006CV-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, ±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 HIP6006CV-T datasheet, HIP6006CV-T pinout, HIP6006CV-T application, or HIP6006CV-T equivalent, key selection considerations include its 14-pin TSSOP package, 200kHz programmable oscillator (50kHz–1MHz), 15MHz error amplifier GBW, 6V/µs slew rate, and integrated soft-start with 10µA current source - all critical for fast transient response in low-voltage, high-current CPU core supplies.
Technical Context
The HIP6006CV-T 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). Its oscillator operates at 200kHz free-running frequency, adjustable via external RT resistor between 50kHz and >1MHz.
Over-current protection is implemented by monitoring the upper MOSFET's rDS(ON) voltage drop against a programmable threshold set by OCSET pin current (200µA typ.) and external ROCSET resistor - eliminating need for sense resistors. Soft-start is controlled by an internal 10µA current source charging an external capacitor on SS pin to 4V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HIP6004CV-T | Same 14-pin TSSOP package; lacks PVCC pin and separate lower gate bias - LGATE powered from VCC only | Lower gate drive strength and reduced noise immunity; unsuitable for high-frequency, high-current POL where PVCC decoupling is critical | Select HIP6006CV-T when independent PVCC bias is required for robust LGATE drive in noisy environments |
| ISL6522CBZ-T | Intersil successor with enhanced 300kHz–1.5MHz oscillator, 20MHz GBW, and improved thermal performance in same footprint | Supports higher switching frequencies and faster transients; requires updated compensation but maintains pin compatibility for upgrade paths | Choose ISL6522CBZ-T for new designs targeting higher efficiency or smaller magnetics; HIP6006CV-T remains valid for legacy-replacement or cost-sensitive builds |
Compared with HIP6004CV-T, the HIP6006CV-T provides superior lower gate drive isolation via dedicated PVCC, improving noise rejection in dense layouts; versus ISL6522CBZ-T, it offers proven field reliability and simpler compensation at the expense of slightly lower bandwidth and frequency range.

FAQ
What is the recommended operating voltage range for the VCC pin of the HIP6006CV-T?
The HIP6006CV-T requires a nominal +12V supply on the VCC pin, with a specified operating range of +12V ±10% (10.8V to 13.2V). Absolute maximum rating is +15.0V. Operation outside this range may cause improper biasing of internal circuits or permanent damage. The HIP6006CV-T does not support direct +5V operation on VCC - a separate +5V or +12V supply must be provided to PVCC for the lower gate driver.
How does the HIP6006CV-T implement over-current protection without a sense resistor?
The HIP6006CV-T uses the upper MOSFET's intrinsic rDS(ON) as a current-sensing element. An internal 200µA current source pulls down the OCSET pin, developing a voltage across an external ROCSET resistor. When the voltage drop across the upper MOSFET (PHASE-to-UGATE) exceeds that across ROCSET, the HIP6006CV-T triggers hiccup-mode soft-start cycling. This method eliminates external sense resistors, reducing power loss and PCB area while maintaining accurate trip thresholds calibrated to MOSFET on-resistance.
Can the HIP6006CV-T operate with a 50kHz switching frequency, and how is it configured?
Yes, the HIP6006CV-T supports 50kHz operation via the RT pin. To achieve ~50kHz, connect a 200kΩ resistor from RT to GND (per Fs ≈ 200kHz × 5 / RT[kΩ]). The datasheet confirms full programmability from below 50kHz to over 1MHz. Lower frequencies reduce switching losses and EMI but increase inductor and capacitor size; the HIP6006CV-T's wide range allows optimization for thermal, size, and efficiency constraints in each application.
What is the function of the PVCC pin on the HIP6006CV-T, and why is it separate from VCC?
The PVCC pin supplies dedicated bias to the lower gate driver (LGATE), electrically isolated from the main VCC rail. This separation prevents switching noise from the power stage from coupling into the logic and upper gate driver circuits. In the HIP6006CV-T, PVCC can accept +5V or +12V and improves LGATE drive strength and noise immunity - especially critical in high-current, high-frequency synchronous buck converters where ground bounce and supply ripple could otherwise disrupt low-side switching timing.
Does the HIP6006CV-T support both bootstrap and direct-drive configurations for the upper MOSFET gate?
Yes, the HIP6006CV-T supports both configurations. For bootstrap drive, connect BOOT to a capacitor charged via a diode from VCC, with PHASE tied to the upper MOSFET source - enabling standard N-MOSFET use. For direct drive (only with ≤+5V input), connect UGATE directly to VCC and omit the bootstrap circuit; this limits gate-to-source voltage but simplifies layout. The HIP6006CV-T's dual capability increases design flexibility across input voltage ranges while maintaining robust gate drive performance in either mode.
