Description and Introduction

Intermediate Bus PWM Controller The ISL6744AB 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:** 1A (peak)  
- **Propagation Delay:** 50ns (typical)  
- **Oscillator Accuracy:** ±6% (over temperature)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Options:** SOIC-16, QFN-16  

### **Descriptions:**
- The ISL6744AB is a dual-output synchronous buck PWM controller designed for high-efficiency DC-DC power supplies.  
- It supports voltage-mode control with adjustable slope compensation.  
- Features include programmable dead-time control, soft-start, and cycle-by-cycle current limiting.  
- Suitable for applications such as telecom, industrial power supplies, and computing systems.  

### **Features:**
- **Dual Independent PWM Outputs** (for synchronous buck topologies)  
- **Adjustable Switching Frequency** (50kHz to 1MHz)  
- **Programmable Dead-Time Control**  
- **Voltage-Mode Control with Slope Compensation**  
- **Cycle-by-Cycle Overcurrent Protection**  
- **Soft-Start Functionality**  
- **Under-Voltage Lockout (UVLO) Protection**  
- **Synchronization Capability** (for multi-phase operation)  
- **Low Power Consumption** (typically 5mA)  

The ISL6744AB is optimized for high-performance power conversion with precise control and protection features.
