Description and Introduction

Dual Output LNB Supply and Control Voltage Regulator with I2C Interface for Advanced Satellite Set-top Box Designs The ISL6405EEB is a synchronous buck 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 28V  
- **Output Voltage Range:** Adjustable from 0.8V to 5.5V  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Maximum Duty Cycle:** 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead QSOP  

### **Descriptions:**
- The ISL6405EEB is a high-efficiency, synchronous buck PWM controller designed for DC-DC voltage regulation.  
- It supports step-down conversion for applications such as telecom, networking, and industrial power supplies.  
- The device integrates MOSFET drivers and provides precise voltage regulation with adjustable frequency.  

### **Features:**
- **Synchronous Rectification:** Improves efficiency by reducing conduction losses.  
- **Adjustable Frequency:** Allows optimization for efficiency and component size.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Overcurrent Protection (OCP):** Safeguards against excessive load currents.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within input voltage limits.  
- **Power-Good Output:** Monitors output voltage status.  
- **Low Shutdown Current:** Reduces power consumption when disabled.  

This information is based on the manufacturer's datasheet. For detailed application notes, refer to the official documentation.
