Description and Introduction

Power Management IC (PMIC) for Li-Ion Powered Systems 32-VQFN -40 to 85 The TPS650243RHBR is a power management IC (PMIC) manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from TI's knowledge base:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 6.0V  
- **Output Voltage:**  
  - Buck Converters (3x): Adjustable (0.8V to 3.3V)  
  - LDOs (2x): Adjustable (1.0V to 3.3V)  
- **Buck Converter Efficiency:** Up to 95%  
- **Switching Frequency:** 2.25MHz (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-pin VQFN (RHBR)  

### **Descriptions:**  
The TPS650243RHBR is a highly integrated PMIC designed for portable applications, providing multiple power rails from a single Li-Ion or Li-Polymer battery. It includes three step-down converters (buck regulators) and two low-dropout linear regulators (LDOs), along with power sequencing and control features.

### **Features:**  
- Three high-efficiency **buck converters** with up to 95% efficiency.  
- Two **low-noise LDOs** for noise-sensitive applications.  
- **I²C-compatible interface** for dynamic voltage scaling and control.  
- **Power sequencing** support for controlled startup/shutdown.  
- **Overcurrent and thermal protection** for reliability.  
- **Low quiescent current** in standby mode for extended battery life.
