Description and Introduction

3-CHANNEL POWER SUPPLY SUPERVISOR The TPS5511D is a step-down DC/DC converter manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 36V  
- **Output Voltage Range:** Adjustable from 1.22V to 31V  
- **Output Current:** Up to 1.5A  
- **Switching Frequency:** 500kHz (fixed)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOIC-8 (D)  

### **Descriptions:**  
The TPS5511D is a monolithic synchronous buck converter designed for high-efficiency, step-down voltage regulation. It integrates a high-side and low-side MOSFET, reducing external component count. The device operates in continuous conduction mode (CCM) and includes features like soft-start, thermal shutdown, and cycle-by-cycle current limiting.  

### **Features:**  
- Integrated 150mΩ high-side and 80mΩ low-side MOSFETs  
- Adjustable output voltage via external resistors  
- Internal soft-start for controlled startup  
- Under-voltage lockout (UVLO) protection  
- Thermal shutdown protection  
- Cycle-by-cycle current limiting  
- Fixed-frequency PWM operation  

This information is based solely on the manufacturer's datasheet.
