Product details
Overview
HIP6004BCB from Intersil is a synchronous-rectified buck PWM controller with integrated voltage-mode regulation, 5-bit TTL-compatible DAC for output voltage selection (1.3V–3.5V), ±1% output regulation over line/temperature, and MOSFET rDS(ON)-based overcurrent sensing. It drives two N-channel MOSFETs in high-performance microprocessor power supplies, such as Pentium Pro and PowerPC™ systems.
For engineers reviewing the HIP6004BCB datasheet, HIP6004BCB pinout, HIP6004BCB application, or HIP6004BCB equivalent, key selection considerations include its 200kHz free-running oscillator (adjustable 50kHz–1MHz), 15MHz error amplifier GBW, 0%–100% duty cycle capability, and SOIC-20 package compatibility with legacy microprocessor VRM designs.
Technical Context
The HIP6004BCB implements voltage-mode PWM control using a triangle-wave oscillator and high-bandwidth error amplifier (15MHz GBW, 6V/µs slew rate) to achieve fast transient response in synchronous buck converters. Its DAC-based reference (VID0–VID4) sets both output voltage and protection thresholds (PGOOD ±10%, OVP at 115% DACOUT).
Overcurrent protection uses an internal 200µA current source at OCSET to sense upper-MOSFET rDS(ON), eliminating external sense resistors. Fault handling employs hiccup-mode soft-start cycling, while OVP triggers an external SCR via the open-drain OVP pin - not internal crowbar circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Oscillator Frequency | 200kHz nominal (adjustable 50kHz–1MHz via RT resistor); enables optimized EMI and efficiency trade-offs. |
| Output Voltage Range | 1.3V–3.5V in 0.05V steps (1.3V–2.05V) and 0.1V steps (2.1V–3.5V); supports Intel VRM 8.x–9.x compatible microprocessor core voltages. |
| Voltage Regulation Accuracy | ±1% over line voltage and temperature; ensures stable core supply under varying input and thermal conditions. |
| Error Amplifier GBW | 15MHz gain-bandwidth product; provides high loop bandwidth for sub-microsecond transient recovery in CPU power delivery. |
| Duty Cycle Range | 0%–100%; allows full-range output voltage control including dropout operation during low-VIN conditions. |
| Power-Good Threshold | ±10% window around DACOUT with 2% hysteresis; prevents PGOOD oscillation due to output ripple. |
| Supply Voltage | +12V ±10% (VCC); compatible with standard ATX 12V rail without auxiliary bias generation. |
Pinout & Package
HIP6004BCB is housed in a 20-lead SOIC package (JEDEC MS-013, pkg drawing M20.3), with exposed pad omitted - distinct from QFN variants. Pin functions are validated per FN4567 Rev 3.00 datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VSEN (1) | Output voltage feedback sense | Direct connection to converter output; feeds PGOOD comparator and OVP circuit - no external divider required. |
| OCSET (2) | Overcurrent threshold programming | Internal 200µA current source develops voltage across ROCSET; trip point determined by rDS(ON) of upper MOSFET. |
| SS (3) | Soft-start timing control | 10µA internal current charges external CSS capacitor; controls ramp-up time and prevents inrush current. |
| VID0–VID4 (4–8) | DAC digital input | TTL-compatible 5-bit bus sets DACOUT reference; defines output voltage, PGOOD, and OVP thresholds per Table 1. |
| COMP (9) | Error amplifier output | Drives external compensation network; connects to FB through RC/ZFB to stabilize voltage-mode loop. |
| FB (10) | Error amplifier inverting input | Connected to VSEN via resistor divider only if DAC is unused; otherwise bypassed when VID pins configure DACOUT. |
| RT (20) | Oscillator frequency set | Resistor to GND increases frequency; resistor to VCC decreases it - enables precise switching frequency tuning. |
Key Features
| Feature | Design Value |
|---|---|
| rDS(ON)-based current sensing | Eliminates external sense resistor, reducing BOM cost and PCB area while preserving efficiency in high-current CPU rails. |
| Integrated 5-bit VID DAC | Enables discrete, software-configurable output voltage selection without external DAC or DAC interface logic. |
| 0%–100% PWM duty cycle | Supports deep dropout operation during low-input-voltage conditions and enables seamless transition between active and sleep states. |
| Hiccup-mode overcurrent protection | Auto-retries after fault clearance; limits average power dissipation during sustained overload without latching shutdown. |
| Single-supply +12V operation | Removes need for auxiliary +5V bias rail - simplifies power architecture in server/desktop motherboards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL6522CRZ | Single-phase controller with integrated MOSFET drivers; supports 3-bit VID (8 voltage levels) vs. HIP6004BCB's 5-bit (32 levels); lacks rDS(ON) sensing - requires external sense resistor. | Targeted at lower-complexity VRM 9.x implementations; not suitable for legacy VRM 8.x systems requiring fine-grained 0.05V steps. | Select ISL6522CRZ only when migrating to newer VRM specs and accepting reduced voltage granularity and added BOM cost. |
| TPS51116PWR | Single-phase controller with 5-bit VID, but uses dedicated current-sense amplifier (not rDS(ON)); includes integrated LDO for gate driver bias; operates from 3.3V/5V bias, not +12V only. | Designed for notebook CPU VRMs with tighter layout constraints; lacks OVP SCR drive and has different soft-start architecture. | Choose TPS51116PWR for portable applications needing dual-bias support and higher integration, but verify OVP and protection feature alignment. |
Compared with HIP6004BCB, ISL6522CRZ offers simpler layout but sacrifices voltage resolution and adds sensing components, while TPS51116PWR improves bias flexibility and integration at the cost of legacy VRM compatibility and direct OVP SCR control.

FAQ
What is the operating temperature range for the HIP6004BCB?
The HIP6004BCB is specified for an ambient temperature range of 0°C to +70°C, as confirmed in the Ordering Information table on page 2 of FN4567 Rev 3.00. This commercial-grade rating aligns with desktop and industrial motherboard applications where airflow and heatsinking maintain junction temperatures below the absolute maximum of 150°C.
Does the HIP6004BCB support both +5V and +12V VCC supply inputs?
No - the HIP6004BCB requires a +12V ±10% supply on the VCC pin (Pin 18), as stated in the Recommended Operating Conditions on page 4 of FN4567 Rev 3.00. 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; VCC must be +12V.
Can the HIP6004BCB be used with modern processors requiring VRM 10.x or IMVP-7 compliance?
No - the HIP6004BCB predates VRM 10.x and IMVP-7 standards. Its 5-bit VID interface, fixed ±10% PGOOD window, and lack of IMVP-specific features (e.g., SVID, phase shedding, telemetry) make it incompatible with post-2006 processor families. It is explicitly marked "NOT RECOMMENDED FOR NEW DESIGNS" in the datasheet.
How does overcurrent protection work on the HIP6004BCB without a sense resistor?
The HIP6004BCB uses the upper MOSFET's rDS(ON) as a current-sense element. An internal 200µA current source at OCSET (Pin 2) develops a voltage across an external resistor (ROCSET). When the voltage drop across the MOSFET exceeds that across ROCSET, the controller initiates hiccup-mode soft-start cycling - verified in the Functional Description section on page 7 of FN4567 Rev 3.00.
Is the HIP6004BCB RoHS compliant?
Yes - the HIP6004BCBZ variant (Pb-free) is RoHS compliant, using 100% matte tin plating and RoHS-compliant molding compounds, as documented in the Ordering Information note on page 2 of FN4567 Rev 3.00. The standard HIP6004BCB is leaded but remains compatible with Pb-free reflow profiles per JEDEC J-STD-020C.
