Description and Introduction

Advanced Single Synchronous Buck Pulse-Width Modulation (PWM) Controller The ISL6420IR-T is a dual-output regulator manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 5.5V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V (for both outputs)  
- **Output Current:** Up to 4A (combined for both outputs)  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead QFN (Quad Flat No-Lead)  

### **Descriptions:**  
- The ISL6420IR-T is a dual synchronous buck regulator designed for point-of-load (POL) applications.  
- It integrates two PWM controllers with MOSFET drivers, enabling compact power supply designs.  
- It supports adjustable output voltages via external resistor dividers.  
- The device includes overcurrent protection, undervoltage lockout (UVLO), and thermal shutdown.  

### **Features:**  
- **Dual Independent Outputs:** Two regulated outputs with individual enable controls.  
- **Adjustable Frequency:** Allows optimization for efficiency or component size.  
- **Integrated MOSFET Drivers:** Reduces external component count.  
- **Power Good Indicators:** Monitors each output voltage.  
- **Soft-Start:** Prevents inrush current during startup.  
- **Synchronization Capability:** Can sync to an external clock.
