- **Operating Frequency Range:** Up to 1MHz  
- **Duty Cycle Range:** 0% to 100%  
- **Output Drive Current:** ±2A (peak)  
- **Propagation Delay:** 50ns (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 8-lead SOIC  

### **Descriptions:**
- The ISL6740IB is a voltage-mode PWM controller designed for high-efficiency power supply applications.  
- It provides precise control for DC-DC converters, including synchronous rectification.  
- Features include adjustable dead-time control, soft-start, and cycle-by-cycle current limiting.  

### **Features:**
- **Voltage-Mode Control:** Ensures stable and accurate regulation.  
- **Adjustable Dead-Time:** Allows optimization of efficiency in synchronous rectifier applications.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Cycle-by-Cycle Current Limiting:** Protects against overcurrent conditions.  
- **High-Speed Operation:** Supports switching frequencies up to 1MHz.  
- **Wide Input Voltage Range:** Suitable for various power supply designs.  
- **Low Propagation Delay:** Enhances transient response.  

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