Description and Introduction

Optoisolated feedback amplifier. The TPS5904A is a step-down converter manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 4.5 V to 28 V  
- **Output Voltage Range:** 0.8 V to 5.5 V (adjustable)  
- **Output Current:** Up to 4 A  
- **Switching Frequency:** 500 kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 20-pin HTSSOP (PowerPAD™)  

### **Descriptions:**  
- The TPS5904A is a synchronous buck converter designed for high-efficiency power conversion.  
- It integrates low-side and high-side MOSFETs for compact designs.  
- Operates in forced PWM mode for stable output under varying loads.  
- Includes features like soft-start, overcurrent protection, and thermal shutdown.  

### **Features:**  
- **Integrated MOSFETs:** Reduces external component count.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Power Good Indicator:** Monitors output voltage status.  
- **Undervoltage Lockout (UVLO):** Ensures proper startup.  
- **Thermal Shutdown Protection:** Prevents overheating.  
- **Forced PWM Operation:** Minimizes output ripple.  

This information is based on TI's official documentation for the TPS5904A. For detailed application notes, refer to the datasheet.
