Description and Introduction

Advanced PWM and Dual Linear Power Control with Integrated ACPI Support Interface The HIP6028CB is a power management controller manufactured by **Intersil** (now part of **Renesas Electronics**). Below are its key specifications:

- **Function**: Multi-phase PWM controller for VRM (Voltage Regulator Module) applications.  
- **Input Voltage Range**: Supports **4.5V to 12V** for the IC's operation.  
- **Output Voltage Range**: Adjustable from **1.3V to 3.5V** (for CPU core voltage regulation).  
- **Phases**: Supports **2 to 4-phase** synchronous buck converter configurations.  
- **Switching Frequency**: Adjustable up to **1MHz per phase**.  
- **Features**:  
  - Precision voltage regulation (±1% over temperature).  
  - Integrated MOSFET drivers.  
  - Overcurrent, overvoltage, and undervoltage protection.  
  - Programmable soft-start.  
  - Differential remote voltage sensing.  
- **Package**: 28-pin **SOIC (CB suffix)**.  
- **Applications**: High-performance desktop/workstation CPUs, DDR memory power supplies.  

Note: Always verify datasheet details from the manufacturer for exact specifications.

Application Scenarios & Design Considerations

Advanced PWM and Dual Linear Power Control with Integrated ACPI Support Interface

Alternative Part Number

  • ISL6520CB --: Same vendor single-phase synchronous buck PWM controller in the same family lineage, functionally similar to the HIP6028 and often used as a direct replacement in similar applications.
  • ISL6522CB --: Intersil synchronous buck controller with comparable voltage-mode PWM control and gate drive, suitable for similar DC-DC converter designs.
  • LM2642MTC --: Dual-channel synchronous buck controller from a different series that can serve as a cross-vendor alternative for similar multi-output power supply designs.
