Description and Introduction

4-Phase PWM Controller with 8-Bit DAC Code Capable of Precision DCR Differential Current Sensing The ISL6326BCRZ-T is a dual-output PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 5.5V (VCC)  
- **Output Voltage Range:** Adjustable (depends on external components)  
- **Switching Frequency Range:** 200kHz to 1MHz  
- **Number of Outputs:** 2 (Dual PWM Controller)  
- **Topology:** Synchronous Buck  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 48-Lead QFN (6x6mm)  

### **Descriptions:**  
- Designed for high-efficiency, multi-phase DC-DC voltage regulation.  
- Supports both single-phase and dual-phase operation.  
- Features adaptive voltage positioning (AVP) for improved transient response.  
- Includes integrated MOSFET drivers for synchronous buck converters.  

### **Features:**  
- **Dual PWM Outputs:** Independent control for two synchronous buck converters.  
- **Adjustable Switching Frequency:** Configurable from 200kHz to 1MHz.  
- **Precision Voltage Regulation:** ±1% reference accuracy.  
- **Adaptive Voltage Positioning (AVP):** Optimizes transient response.  
- **Integrated MOSFET Drivers:** Reduces external component count.  
- **Overcurrent Protection (OCP):** Monitors and protects against excessive current.  
- **Overvoltage Protection (OVP):** Safeguards against output overvoltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper startup and shutdown.  

This controller is commonly used in power supply applications for servers, telecom equipment, and high-performance computing systems.

Application Scenarios & Design Considerations

4-Phase PWM Controller with 8-Bit DAC Code Capable of Precision DCR Differential Current Sensing

Alternative Part Number

  • ISL6312ACRZ --: Same Intersil/Renesas multiphase PWM controller family with comparable VR11.x features; widely available and a common drop-in choice for similar buck converter designs.
  • NCP5386MNR2G --: Single/dual-phase synchronous buck controller with similar voltage-mode control and current sensing, suitable as a functional cross from the ISL6326 in CPU VR applications.
  • ADP3198JCPZ-RL --: Multiphase buck controller for CPU core power with comparable phase count and VID control, offering an alternative source with different naming and vendor.
