Description and Introduction

3 DC-DC converters with Integrated FET & 2 USB Switches 40-VQFN -40 to 85 The TPS65258RHAR is a power management IC (PMIC) manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from TI's knowledge base:

### **Manufacturer:** Texas Instruments (TI)  
### **Part Number:** TPS65258RHAR  

### **Description:**  
The TPS65258RHAR is a highly integrated PMIC designed for applications requiring multiple power rails. It combines three step-down converters (buck regulators) with a low-dropout (LDO) regulator, providing a compact and efficient power solution.

### **Key Features:**  
1. **Triple Synchronous Buck 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  
   - **Switching Frequency:** 2.25 MHz (typ)  

2. **Integrated LDO Regulator:**  
   - Fixed 3.3V output, 300mA current capability  

3. **Input Voltage Range:**  
   - 2.7V to 6V  

4. **Efficiency Optimization:**  
   - Automatic PFM/PWM mode switching for improved efficiency at light loads  

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

6. **Control & Interface:**  
   - I²C interface for dynamic voltage scaling (DVS) and configuration  
   - Power-good (PG) indicators for each regulator  

7. **Package:**  
   - 40-pin VQFN (RHAR) with exposed thermal pad  

8. **Applications:**  
   - Industrial, consumer, and portable electronics  
   - Processors, FPGAs, and system-on-chip (SoC) power supplies
