Description and Introduction

2 Buck Converter with 4.5V to 16V Input Voltage, 2A/3A Output Current 24-HTSSOP -40 to 85 The TPS65270PWPR is a power management IC (PMIC) manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:** Texas Instruments (TI)  
### **Part Number:** TPS65270PWPR  

### **Description:**  
The TPS65270PWPR is a highly integrated power management IC designed for applications requiring multiple voltage rails. It integrates three step-down DC-DC converters and two LDO regulators, providing a compact power solution for systems such as FPGAs, DSPs, and processors.  

### **Key Features:**  
1. **Three Step-Down DC-DC Converters:**  
   - **Buck 1:** Adjustable output (0.8V to 3.3V), up to 3A  
   - **Buck 2:** Adjustable output (0.8V to 3.3V), up to 2A  
   - **Buck 3:** Adjustable output (0.8V to 3.3V), up to 2A  

2. **Two LDO Regulators:**  
   - **LDO1:** Fixed or adjustable output (1.2V to 3.3V), up to 300mA  
   - **LDO2:** Fixed or adjustable output (1.2V to 3.3V), up to 300mA  

3. **Input Voltage Range:** 4.5V to 18V  

4. **Switching Frequency:** 500kHz to 2.2MHz (adjustable)  

5. **Efficiency:** Up to 95% (depending on load and configuration)  

6. **Protection Features:**  
   - Overcurrent protection (OCP)  
   - Thermal shutdown  
   - Undervoltage lockout (UVLO)  

7. **Control Interface:** I²C-compatible for dynamic voltage scaling and power sequencing  

8. **Package:** 28-pin HTSSOP (PWPR) with PowerPAD™ for improved thermal performance  

9. **Operating Temperature Range:** -40°C to +125°C  

10. **Applications:**  
   - Industrial systems  
   - Networking equipment  
   - Embedded computing  
   - FPGA/DSP power supplies  

This information is based on TI's official datasheet for the TPS65270PWPR. For detailed electrical characteristics and application guidelines, refer to the manufacturer's documentation.
