Description and Introduction

High Performance Industry Standard Single-Ended Current Mode PWM Controller The ISL8843AMZ is a high-performance 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 15V  
- **Operating Frequency Range:** 50kHz to 1MHz  
- **Duty Cycle Range:** 0% to 100%  
- **Output Drive Current:** ±2A (peak)  
- **Switching Frequency Accuracy:** ±10%  
- **Supply Current (Quiescent):** 3.5mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-SOIC  

### **Descriptions:**
- The ISL8843AMZ is a versatile synchronous PWM controller designed for DC-DC power conversion applications.  
- It supports voltage-mode control with adjustable frequency and duty cycle.  
- The device is optimized for high-efficiency power supplies in industrial, telecom, and computing systems.  

### **Features:**
- **Adjustable Frequency:** Allows optimization for efficiency and component size.  
- **Voltage-Mode Control:** Simplifies feedback loop design.  
- **Synchronous Rectification Support:** Enhances efficiency in buck/boost topologies.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **High-Speed Gate Drivers:** Supports fast switching for MOSFETs.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  

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