Description and Introduction

A full featured and flexible way to implement a power solution for the latest high performance CPUs and ASICs. The IR3508MTRPBF 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 5.5V  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Phase Configuration:** Single-phase  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 16-Lead QFN (4mm x 4mm)  
- **Control Method:** Voltage Mode PWM  
- **Features:**  
  - Precision reference voltage (±1%)  
  - Programmable soft-start  
  - Overcurrent protection (OCP)  
  - Overvoltage protection (OVP)  
  - Undervoltage lockout (UVLO)  
  - Power-good indicator  
  - Adjustable switching frequency  

### **Descriptions and Features:**  
The IR3508MTRPBF is designed for high-efficiency synchronous buck DC-DC converters. It supports a wide input voltage range and adjustable output voltage, making it suitable for various power supply applications. The controller includes protection features such as OCP, OVP, and UVLO to enhance system reliability. Its voltage-mode control architecture ensures stable operation across different load conditions. The device is available in a compact QFN package, making it ideal for space-constrained designs.
