Description and Introduction

2-Phase Dual Synchronous PWM Controller with Oscillator Synchronization and Pre-Bias Startup The IR3621MPBF is a synchronous buck PWM controller manufactured by Infineon Technologies. Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 20V  
- **Output Voltage Range:** Adjustable down to 0.6V  
- **Switching Frequency:** Adjustable from 100kHz to 1MHz  
- **Duty Cycle:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin SOIC  

### **Descriptions:**  
- The IR3621MPBF is designed for high-efficiency DC-DC voltage regulation.  
- It supports synchronous rectification for improved efficiency.  
- The controller is suitable for point-of-load (POL) applications.  

### **Features:**  
- **Adjustable Output Voltage:** Via external resistor divider.  
- **Programmable Soft-Start:** Reduces inrush current.  
- **Overcurrent Protection (OCP):** Prevents damage from excessive load.  
- **Overvoltage Protection (OVP):** Safeguards against output voltage spikes.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage range.  
- **Synchronization Capability:** Can sync to an external clock.
