Description and Introduction

Microprocessor CORE Voltage Regulator Multi-Phase Buck PWM Controller The HIP6304CB is a multi-phase PWM controller manufactured by Intersil (now part of Renesas Electronics). Here are its key specifications:

1. **Function**: Multi-phase PWM controller for voltage regulation.  
2. **Phases**: Supports 2, 3, or 4-phase operation.  
3. **Output Voltage Range**: Adjustable from 0.8V to 5.5V.  
4. **Switching Frequency**: Programmable from 50kHz to 1MHz per phase.  
5. **Input Voltage (VCC)**: 12V typical.  
6. **Current Balancing**: Precision current sensing and balancing across phases.  
7. **Protection Features**: Overvoltage, undervoltage, and overcurrent protection.  
8. **Package**: 28-pin SOIC (Small Outline Integrated Circuit).  
9. **Operating Temperature Range**: -40°C to +85°C.  
10. **Applications**: Used in high-performance CPUs, servers, and power supplies.

Application Scenarios & Design Considerations

Microprocessor CORE Voltage Regulator Multi-Phase Buck PWM Controller

Alternative Part Number

  • ISL6556BCBZ --: Multi-phase PWM controller from the ISL series that serves as the direct successor to the HIP630x family, with similar voltage-mode control and VID interface, available in the same SOIC package.
  • ISL6566CRZ --: Three-phase buck controller with integrated gate drivers and comparable VID/DAC programming, a common drop-in upgrade path for HIP6304-based VRM designs.
  • ADP3180JRUZ --: Analog Devices multi-phase synchronous buck controller with similar VID-controlled output and phase-count flexibility, usable as a cross-vendor replacement for HIP6304 applications.
  • NCP5381MNR2G --: Two-phase synchronous buck controller from a different vendor with similar multi-phase VRM control role; requires careful comparison of VID, current sensing, and gate drive specs.
