Description and Introduction

The IR3506 Phase IC combined with IR3522 xPHASE3 Control ICs implements a full featured DDR3 power solution. The IR3506MTRPBF is a synchronous buck PWM controller manufactured by Infineon Technologies (formerly International Rectifier).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 21V  
- **Output Voltage Range:** 0.6V to 85% of VIN  
- **Switching Frequency:** Adjustable from 100kHz to 1MHz  
- **Duty Cycle Range:** 0% to 85%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead QFN (5mm x 5mm)  
- **Control Method:** Voltage Mode PWM  
- **Gate Drive Voltage:** 5V  
- **Protection Features:** Overcurrent Protection (OCP), Overvoltage Protection (OVP), Undervoltage Lockout (UVLO)  

### **Descriptions and Features:**  
- Designed for high-efficiency synchronous buck DC-DC converters.  
- Supports pre-biased output startup.  
- Adjustable soft-start for controlled power-up.  
- Precision reference voltage (0.6V ±1%).  
- Integrated bootstrap diode for high-side MOSFET drive.  
- Supports diode emulation for improved light-load efficiency.  
- Compatible with both N-channel MOSFETs.  
- Low shutdown current (<10µA).  

The IR3506MTRPBF is commonly used in point-of-load (POL) regulators, servers, telecom equipment, and industrial applications.
