Product details
Overview
HIP6004ECBZ from Renesas (formerly Intersil) is a synchronous-rectified buck PWM controller with integrated voltage-mode regulation, output voltage monitoring, and MOSFET gate drivers for high-performance microprocessor VRM applications. It supports 1.05V–1.825V output via 5-bit VID DAC (25mV steps), delivers 0%–100% duty cycle control, features ±1% output regulation over line/temperature, and operates from +12V supply with 200kHz programmable oscillator (50kHz–1MHz).
For engineers reviewing the HIP6004ECBZ datasheet, HIP6004ECBZ pinout, HIP6004ECBZ application, or HIP6004ECBZ equivalent, key selection considerations include its rDS(ON)-based overcurrent sensing, PGOOD window comparator (±10%), OVP-triggered external SCR crowbar, soft-start current source (10μA), and compatibility with N-channel upper/lower MOSFETs in SOIC-20 package.
Technical Context
The HIP6004ECBZ implements voltage-mode PWM control using a 15MHz GBWP error amplifier and 6V/μs slew rate to achieve fast transient response. Its 200kHz free-running oscillator is adjustable via RT pin resistor (50kHz–1MHz range), and the internal 5-bit DAC sets both output voltage and protection thresholds (PGOOD/OVP).
Overcurrent protection uses the upper MOSFET's rDS(ON) with an internal 200μA current source at OCSET pin - eliminating external sense resistors. Fault handling employs hiccup-mode soft-start cycling, while OVP triggers an open-drain OVP pin to drive an external SCR for input crowbar protection.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSEN (1) | Output voltage sense input | Direct connection to converter output; feeds PGOOD and OVP comparators - enables accurate tracking of regulated voltage |
| OCSET (2) | Overcurrent threshold programming | Connects to upper MOSFET drain via ROCSET; internal 200μA current source sets IPEAK trip point using rDS(ON) |
| SS (3) | Soft-start timing node | 10μA internal current source charges external CSS capacitor - controls ramp-up time and prevents inrush current |
| VID25mV–VID3 (4–8) | DAC input bits | 5-bit TTL-compatible interface (0 = GND, 1 = pulled up) - selects one of 32 discrete output voltages between 1.05V and 1.825V |
| COMP (9) | Error amplifier output | Drives external compensation network - connects to FB through RC/Z network to stabilize voltage-mode loop |
| FB (10) | Error amplifier inverting input | Connected to VSEN via resistor divider - forms feedback path for regulation; referenced to DACOUT |
| GND (11) | Signal ground reference | Common return for all analog and logic circuits - must be low-impedance connection to minimize noise coupling |
| PGOOD (12) | Open-collector status output | Pulled low when VSEN deviates >±10% from DACOUT - used for system power sequencing and fault indication |
| PHASE (13) | High-side switch node monitor | Connected to upper MOSFET source - provides return path for UGATE drive and enables rDS(ON) current sensing |
| UGATE (14) | Upper MOSFET gate driver output | 500mA typical source/sink capability - drives N-channel high-side FET with bootstrap-assisted level shift |
| BOOT (15) | Bootstrap supply input | Accepts charge from external bootstrap capacitor - generates floating rail for UGATE driver above PHASE voltage |
| PGND (16) | Power ground return | Low-inductance return for lower MOSFET source and gate drive - separate from signal GND to avoid noise injection |
| LGATE (17) | Lower MOSFET gate driver output | 450mA typical source/sink - directly drives N-channel synchronous rectifier with minimal dead-time requirements |
| VCC (18) | Bias supply input | +12V ±10% supply for internal circuitry and gate drivers - requires local 10μF ceramic decoupling |
| OVP (19) | Overvoltage protection output | Open-drain output that sources 60mA when VSEN exceeds 115% DACOUT - triggers external SCR crowbar |
| RT (20) | Oscillator frequency set | Internal 1.26V reference; resistor to GND increases frequency, resistor to VCC decreases it - enables precise switching frequency tuning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL6522CBZ | Same manufacturer (Intersil/Renesas), 20-pin SOIC, supports 0.9V–2.5V output, includes integrated MOSFET drivers but lacks VID DAC - requires external DAC or resistor programming | Targeted at broader voltage range applications; not VRM8.5-compliant due to missing VID interface | Select ISL6522CBZ only if fixed or externally programmed output voltage suffices and VRM8.5 VID protocol is unnecessary |
| TPS51100PWR | Texas Instruments part; 20-pin TSSOP, supports 0.9V–1.8V, includes VID interface but uses different DAC encoding (4-bit + offset) and lacks OVP crowbar output | Designed for DDR memory termination and low-power CPUs; no external SCR crowbar support limits fault containment capability | Choose TPS51100PWR for cost-sensitive, non-critical applications where full overvoltage fail-safe is not required |
Compared with ISL6522CBZ and TPS51100PWR, the HIP6004ECBZ uniquely combines VRM8.5-compliant 5-bit VID DAC, rDS(ON) current sensing, and OVP-triggered crowbar protection - making it the only option among the three qualified for Pentium III-era microprocessor power delivery with full safety redundancy.

FAQ
What is the operating temperature range for the HIP6004ECBZ?
The HIP6004ECBZ is specified for operation from 0°C to +70°C ambient temperature. This range aligns with commercial-grade requirements for desktop and embedded microprocessor power applications. The device's thermal resistance (θJA) is 65°C/W in the SOIC-20 package, enabling reliable operation within this range when proper PCB copper area and airflow are maintained. Exceeding 70°C ambient may trigger thermal shutdown or degrade regulation accuracy.
How does the HIP6004ECBZ implement overcurrent protection without a sense resistor?
The HIP6004ECBZ uses the upper MOSFET's intrinsic on-resistance (rDS(ON)) as the current-sensing element. An internal 200μA current source at the OCSET pin develops a voltage across an external resistor (ROCSET); when the voltage drop across the upper MOSFET exceeds this reference, the controller initiates hiccup-mode soft-start cycling. This method eliminates external sense resistors, reducing power loss and BOM cost while maintaining accurate peak-current limiting for the HIP6004ECBZ.
Can the HIP6004ECBZ be used with a +5V input supply instead of +12V?
No - the HIP6004ECBZ requires a +12V ±10% supply on the VCC pin for proper operation of its gate drivers and internal circuitry. While the datasheet notes the controller is "designed to operate from +5V or +12V input," this refers to the main converter input (VIN), not the bias supply. The VCC pin must be supplied with +12V; using +5V will result in insufficient gate drive strength, degraded error amplifier performance, and potential functional failure of the HIP6004ECBZ.
What is the purpose of the VID25mV pin on the HIP6004ECBZ?
The VID25mV pin is the most significant bit (MSB) of the 5-bit VID DAC interface on the HIP6004ECBZ. Together with VID0–VID3, it defines one of 32 discrete output voltage levels between 1.05V and 1.825V in 25mV increments. Unlike standard VID protocols, VID25mV enables finer resolution by extending the DAC beyond 4 bits - ensuring precise compliance with VRM8.5 specifications for Pentium III microprocessors. Its state (high/low) directly impacts DACOUT voltage and thus PGOOD/OVP thresholds.
Does the HIP6004ECBZ support synchronous rectification with external MOSFETs only?
Yes - the HIP6004ECBZ is explicitly designed to drive two external N-channel MOSFETs in a synchronous-buck topology: the upper MOSFET is driven by UGATE/BOOT/PHASE, and the lower MOSFET by LGATE/PGND. It does not integrate power switches. The controller provides matched 500mA (UGATE) and 450mA (LGATE) peak gate drive currents, supports bootstrap high-side drive, and includes built-in shoot-through prevention logic - all optimized for discrete synchronous rectifier implementations in the HIP6004ECBZ.
