Description and Introduction

Single Synchronous Buck Pulse-Width Modulation (PWM) Controller The ISL6426IB is a dual-output regulator manufactured by INTERSIL (now part of Renesas Electronics). Below are its specifications, descriptions, and features based on the available knowledge:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 5.5V  
- **Output Voltage Range (Adjustable):** 0.8V to 5.5V  
- **Output Current:** Up to 4A per channel (total 8A)  
- **Switching Frequency:** 300kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-Lead QFN (5mm x 5mm)  

### **Descriptions:**  
- The ISL6426IB is a high-efficiency, dual-output synchronous buck regulator designed for point-of-load (POL) applications.  
- It integrates two independent regulators with PWM control for precise voltage regulation.  
- Features include overcurrent protection, thermal shutdown, and undervoltage lockout (UVLO).  

### **Features:**  
- **Dual Independent Outputs:** Two synchronous buck regulators in a single package.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **High Efficiency:** Uses synchronous rectification for reduced power loss.  
- **Protection Features:** Overcurrent, thermal shutdown, and UVLO.  
- **Soft-Start:** Prevents inrush current during startup.  
- **Power-Good Indicators:** Monitors output status for each channel.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed application notes, refer to the official datasheet from Renesas Electronics (formerly INTERSIL).
