Description and Introduction

8V to 14V, Single-Phase Synchronous Buck Pulse-Width Modulation PWM Controller With Integrated Gate Drivers The ISL8104CBZ is a synchronous buck PWM controller 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:**  
- **Input Voltage Range:** 4.5V to 14V  
- **Output Voltage Range:** Adjustable down to 0.6V  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Maximum Duty Cycle:** 100%  
- **Output Current:** Up to 30A (with external MOSFETs)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead SOIC  

### **Descriptions:**  
- The ISL8104CBZ is a high-performance synchronous buck PWM controller designed for DC-DC voltage regulation.  
- It supports a wide input voltage range, making it suitable for various power supply applications.  
- The controller uses voltage-mode control with adjustable switching frequency for optimized performance.  
- It includes features like overcurrent protection, undervoltage lockout (UVLO), and soft-start to enhance system reliability.  

### **Features:**  
- **Adjustable Output Voltage:** Supports output voltages as low as 0.6V.  
- **Programmable Switching Frequency:** Allows optimization for efficiency and component size.  
- **Voltage-Mode Control:** Provides stable regulation with external compensation.  
- **Overcurrent Protection (OCP):** Prevents damage due to excessive load current.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Power Good Indicator:** Monitors output voltage status.
