Description and Introduction

Flexible Double Ended Voltage and Current Mode PWM Controllers The ISL6741IB 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 5.5V (VDD)  
- **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:** 8-lead SOIC  

### **Descriptions:**  
The ISL6741IB is a **voltage-mode PWM controller** designed for high-efficiency power supply applications. It provides precise control for DC-DC converters, supporting synchronous rectification and adjustable dead-time control.  

### **Features:**  
- **Voltage-Mode Control** with adjustable slope compensation  
- **Programmable Soft-Start** for controlled startup  
- **Synchronous Rectification Support**  
- **Adjustable Dead-Time Control**  
- **Under-Voltage Lockout (UVLO)** protection  
- **High-Speed Error Amplifier** for fast transient response  
- **Low Startup Current** (typically 50µA)  

This PWM controller is commonly used in **switching power supplies, telecom, and industrial applications** due to its high efficiency and reliability.  

(Note: Always refer to the official datasheet for detailed specifications.)

Description and Introduction

Flexible Double Ended Voltage and Current Mode PWM Controllers The ISL6741IB is a high-performance PWM controller manufactured by Intersil (now part of Renesas Electronics). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 15V  
- **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 +125°C  
- **Package Type:** 16-Lead SOIC  

### **Descriptions:**  
The ISL6741IB is a voltage-mode PWM controller designed for high-efficiency power supply applications. It provides precise control over switching power converters with features like adjustable dead-time control, soft-start, and cycle-by-cycle current limiting. It is commonly used in DC-DC converters, telecom power supplies, and industrial power systems.  

### **Features:**  
- **Voltage-Mode Control:** Ensures stable operation in power supply designs.  
- **Adjustable Dead-Time Control:** Optimizes efficiency by minimizing shoot-through.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Cycle-by-Cycle Current Limiting:** Protects against overcurrent conditions.  
- **Synchronizable Oscillator:** Allows synchronization to an external clock.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **High-Speed Error Amplifier:** Enhances transient response.  

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