Description and Introduction

300kHz Dual, 180 Degree Out-of-Phase, Step-Down PWM and Single Linear Controller The ISL6443IRZ-TK is a dual-output PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 24V  
- **Output Voltage Range:** Adjustable (depends on external components)  
- **Switching Frequency:** 200kHz to 1.5MHz (adjustable)  
- **Output Current:** Supports high-current applications (dependent on external MOSFETs)  
- **Number of Outputs:** Dual (two independent PWM controllers)  
- **Duty Cycle Range:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead QFN (Quad Flat No-Lead)  

### **Descriptions:**  
The ISL6443IRZ-TK is a high-performance dual-output PWM controller designed for DC-DC power supply applications. It integrates two independent voltage-mode controllers, allowing for flexible power supply designs. The device features programmable switching frequency, soft-start, and overcurrent protection.  

### **Features:**  
- **Dual PWM Controllers:** Independent control for two outputs.  
- **Adjustable Switching Frequency:** 200kHz to 1.5MHz.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Overcurrent Protection (OCP):** Enhances system reliability.  
- **Synchronization Capability:** Can sync to an external clock.  
- **Wide Input Voltage Range:** Supports 4.5V to 24V input.  
- **High Efficiency:** Optimized for power conversion applications.  
- **QFN Package:** Compact and suitable for space-constrained designs.
