Description and Introduction

Single Output LNB Supply and Control Voltage Regulator with I2C Interface for Advanced Satellite Set-Top Box Designs The ISL6423BERZ 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 1 (Buck Converter):** Adjustable from 0.8V to 3.3V  
- **Output Voltage 2 (LDO Regulator):** Adjustable from 1.25V to 5.5V  
- **Buck Converter Output Current:** Up to 3A  
- **LDO Output Current:** Up to 300mA  
- **Switching Frequency:** 1.5MHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead QFN (4mm x 4mm)  

### **Descriptions:**  
The ISL6423BERZ integrates a high-efficiency synchronous buck regulator and a low-dropout (LDO) linear regulator in a single package. It is designed for applications requiring multiple regulated voltages, such as set-top boxes, networking equipment, and portable devices. The buck converter provides high-current output, while the LDO ensures low-noise performance for sensitive loads.

### **Features:**
