Product details
Overview
HIP6004ECBZ-T from Renesas (formerly Intersil) is a synchronous-rectified buck PWM controller IC designed for high-performance microprocessor VRM8.5 applications. It drives two N-channel MOSFETs, delivers 1.05V–1.825V output via 5-bit VID DAC with ±1% regulation, and features voltage-mode control with 15MHz GBWP error amplifier and 200kHz programmable oscillator (50kHz–1MHz).
For engineers reviewing the HIP6004ECBZ-T datasheet, HIP6004ECBZ-T pinout, HIP6004ECBZ-T application, or HIP6004ECBZ-T equivalent, key selection considerations include its rDS(ON)-based overcurrent sensing, 0%–100% duty cycle capability, PGOOD window monitoring (±10%), OVP-triggered SCR crowbar, and SOIC-20 Pb-free package compatibility with +5V/+12V bias supplies.
Technical Context
The HIP6004ECBZ-T implements voltage-mode PWM control using a 200kHz free-running oscillator adjustable via RT-to-GND or RT-to-VCC resistor networks. Its error amplifier provides 15MHz gain-bandwidth and 6V/µs slew rate to support fast transient response in microprocessor power delivery.
Overcurrent protection operates without external sense resistors by comparing the upper MOSFET's rDS(ON) voltage drop against a reference set by OCSET current (200µA typ.) and ROCSET. Overvoltage protection triggers at 115–120% of DACOUT and activates an external SCR via OVP pin while inhibiting PWM.

| FB (10) | Error amplifier inverting input | Connects to voltage divider from VOUT to set regulation point; forms closed-loop feedback path. |
| GND (11) | Signal ground reference | Reference plane for all analog circuitry; must be low-impedance and separated from PGND where possible. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL6522CBZ-T | Same manufacturer family; includes integrated MOSFET drivers but lacks rDS(ON) OC sensing - requires external sense resistor. | Targeted at higher-current VRM9.x designs with tighter transient specs; not drop-in compatible due to different VID mapping and protection architecture. | Select ISL6522CBZ-T only when upgrading to VRM9.x compliance or when external current sensing is acceptable for improved OC accuracy. |
| TPS51220ARUKR | TI part with integrated LDO bias rail, different VID encoding (6-bit), and no OVP SCR crowbar output - uses internal shutdown instead. | Designed for notebook CPU power with lighter load profiles; lacks the 0–100% duty cycle and high-current gate drive specs of HIP6004ECBZ-T. | Choose TPS51220ARUKR for portable applications needing ultra-low quiescent current and integrated bias generation, not for high-power desktop/server VRMs. |
Compared with ISL6522CBZ-T and TPS51220ARUKR, the HIP6004ECBZ-T uniquely combines rDS(ON)-based overcurrent protection, 5-bit VID DAC with 25mV resolution, and OVP-triggered external SCR crowbar - making it optimal for legacy VRM8.5 systems requiring cost-effective, high-reliability power delivery without added sensing components.

FAQ
What is the primary function of the HIP6004ECBZ-T in a power supply design?
The HIP6004ECBZ-T serves as a synchronous-rectified buck PWM controller IC that manages voltage regulation, MOSFET gate driving, output monitoring, and fault protection for microprocessor core power supplies. It integrates a 5-bit VID DAC, voltage-mode error amplifier, programmable oscillator, and rDS(ON)-based overcurrent detection - all within a single SOIC-20 package. The HIP6004ECBZ-T is essential for achieving VRM8.5 compliance in Pentium III-class systems.
How does the HIP6004ECBZ-T implement overcurrent protection without a sense resistor?
The HIP6004ECBZ-T uses the upper MOSFET's intrinsic on-resistance (rDS(ON)) as the current-sensing element. An internal 200µA current source flows through an external resistor (ROCSET) tied to OCSET, generating a reference voltage. When the voltage drop across the upper MOSFET exceeds this reference, the HIP6004ECBZ-T initiates hiccup-mode soft-start recovery. This method eliminates external sense resistors, reducing losses and PCB area while maintaining accurate trip thresholds calibrated to MOSFET characteristics.
What is the significance of the RT pin on the HIP6004ECBZ-T?
The RT pin on the HIP6004ECBZ-T controls the oscillator frequency: connecting a resistor from RT to GND increases switching frequency (≈200kHz + 5×10⁶/RT kΩ), while connecting it to VCC decreases frequency (≈200kHz – 4×10⁷/RT kΩ). This programmability allows designers to optimize trade-offs between efficiency, EMI, magnetic component size, and thermal performance. The RT pin maintains a constant 1.26V reference, enabling predictable tuning across temperature and process variations.
Can the HIP6004ECBZ-T operate with both +5V and +12V input supplies?
Yes, the HIP6004ECBZ-T is specified to operate with either +5V or +12V bias on the VCC pin, though the recommended condition is +12V ±10%. Its gate drivers (UGATE/LGATE) and internal logic are designed for robust operation across this dual-supply range, supporting flexibility in system-level power architecture. However, the +12V configuration delivers higher gate drive strength and is required for full 0–100% duty cycle capability and optimal transient response in high-current applications.
What does the PGOOD signal indicate, and how is its threshold set on the HIP6004ECBZ-T?
The PGOOD signal on the HIP6004ECBZ-T is an open-drain output that asserts low when the regulated output voltage (monitored at VSEN) falls outside a ±10% window centered on the DACOUT reference voltage. Its upper and lower thresholds are 106–111% and 89–94% of DACOUT respectively, with 2% hysteresis to prevent oscillation due to output ripple. This window is automatically scaled with DACOUT - so changing VID inputs adjusts both the target voltage and PGOOD trip points simultaneously.
