Description and Introduction

Single Output LNB Supply and Control Voltage Regulator with I2C Interface for Advanced Satellite Set-Top Box Designs The ISL6423BEVEZ is a voltage regulator IC manufactured by INTERSIL (now part of Renesas Electronics). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** INTERSIL  
- **Part Number:** ISL6423BEVEZ  
- **Package:** 16-Lead QSOP (QSOP-16)  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable (0.8V to 5.5V)  
- **Output Current:** Up to 4A  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Protection Features:** Overcurrent, Overvoltage, Undervoltage Lockout (UVLO), Thermal Shutdown  

### **Descriptions:**  
The ISL6423BEVEZ is a synchronous buck PWM controller designed for high-efficiency DC-DC voltage regulation. It is optimized for point-of-load (POL) applications, providing precise voltage regulation for powering microprocessors, FPGAs, and other digital ICs. The device supports adjustable output voltage and frequency, making it versatile for various power supply designs.

### **Features:**  
- **Synchronous Buck Controller:** Improves efficiency by reducing power dissipation.  
- **Wide Input Voltage Range (4.5V–28V):** Suitable for various power sources.  
- **Adjustable Output Voltage (0.8V–5.5V):** Supports multiple load requirements.  
- **High Efficiency (Up to 95%):** Minimizes power loss.  
- **Programmable Switching Frequency (300kHz–1MHz):** Allows optimization for size and efficiency.  
- **Integrated Protection:** Includes overcurrent, overvoltage, UVLO, and thermal shutdown.  
- **External MOSFET Drive:** Supports high-current applications.  
- **Soft-Start Function:** Reduces inrush current during startup.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
