Description and Introduction

TPS54352/3/4/5/6/7: 4.5-V to 20-V Input, 3-A Output Synchronous PWM Switcher The TPS54353PWP is a step-down (buck) DC-DC converter manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** 0.8V to 25V (adjustable)  
- **Output Current:** Up to 3A (continuous)  
- **Switching Frequency:** 300 kHz to 2.2 MHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** HTSSOP-14 (PWP)  

### **Descriptions:**  
- The TPS54353PWP is a synchronous buck converter with integrated high-side and low-side MOSFETs.  
- It supports a wide input voltage range, making it suitable for industrial, automotive, and telecom applications.  
- Features include adjustable frequency, soft-start, and thermal shutdown protection.  

### **Features:**  
- **Integrated MOSFETs:** Reduces external component count.  
- **Adjustable Switching Frequency:** Allows optimization for efficiency and size.  
- **Soft-Start:** Prevents inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage.  
- **Thermal Shutdown Protection:** Safeguards against overheating.  
- **Synchronous Rectification:** Improves efficiency compared to diode-based designs.
