Description and Introduction

Buck and Synchronous Rectifier Pulse-Width Modulator (PWM) Controller The ISL6522CR is a dual MOSFET driver IC manufactured by Intersil (now part of Renesas Electronics). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Intersil (Renesas Electronics)  
- **Part Number:** ISL6522CR  
- **Type:** Dual MOSFET Driver  
- **Operating Voltage Range:** 4.5V to 13.2V  
- **Output Current (Peak):** 2A (sink/source)  
- **Switching Frequency:** Up to 1MHz  
- **Propagation Delay:** 30ns (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead SOIC  

### **Descriptions:**  
The ISL6522CR is a high-frequency, dual MOSFET driver designed to drive both high-side and low-side N-channel MOSFETs in synchronous buck converter applications. It provides fast switching speeds and low propagation delays, making it suitable for high-efficiency power supply designs.  

### **Features:**  
- **Dual Outputs:** Independently drives high-side and low-side MOSFETs.  
- **Adaptive Shoot-Through Protection:** Prevents cross-conduction.  
- **High-Speed Switching:** Optimized for high-frequency operation.  
- **Wide Input Voltage Range:** Supports 4.5V to 13.2V operation.  
- **Low Propagation Delay:** Ensures precise switching timing.  
- **Under-Voltage Lockout (UVLO):** Protects against low input voltage conditions.  
- **Thermal Shutdown:** Prevents overheating damage.  

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

Application Scenarios & Design Considerations

Buck and Synchronous Rectifier Pulse-Width Modulator (PWM) Controller

Alternative Part Number

  • UC3843AN --: Industry-standard current-mode PWM controller in DIP-8, functionally similar to the ISL6522 synchronous buck controller and widely available as a drop-in style replacement.
  • SG3525AN --: Voltage-mode PWM controller in DIP-16 with totem-pole outputs, suitable for similar power supply control applications where the ISL6522 is used.
  • TL494CN --: Classic general-purpose PWM controller in DIP-16, commonly used as a substitute in DC-DC converter designs when the original ISL6522 is unavailable.
