Description and Introduction

Frontend Power Management IC (PMIC) with Switchmode Charger for 2-3 Cells In Series 100-VQFN-MR -40 to 85 The TPS65090ARVNR is a power management IC (PMIC) manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features based on factual data:  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 6.5V  
- **Output Voltage:**  
  - Buck converters: Adjustable (0.8V to 3.3V)  
  - LDOs: Adjustable (1.0V to 3.3V)  
- **Number of Buck Converters:** 3 (step-down DC/DC converters)  
- **Number of LDOs:** 4 (low-dropout regulators)  
- **Switching Frequency:** 2.25MHz (typical)  
- **Efficiency:** Up to 95% (depending on load and configuration)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-pin VQFN (5mm x 5mm)  

### **Descriptions:**  
The TPS65090ARVNR is a highly integrated PMIC designed for multi-rail power supply applications, particularly in portable and battery-powered systems. It combines three step-down converters and four LDOs to provide efficient power management for processors, FPGAs, and other low-voltage devices.  

### **Features:**  
- **Integrated Power Solution:** Combines buck converters and LDOs in a single chip.  
- **High Efficiency:** Uses synchronous rectification for improved power conversion.  
- **Dynamic Voltage Scaling (DVS):** Supports adjustable output voltages for power optimization.  
- **Power Sequencing:** Configurable startup and shutdown sequencing.  
- **Protection Features:** Includes overcurrent, overtemperature, and undervoltage lockout (UVLO).  
- **Low Quiescent Current:** Optimized for battery-powered applications.  

This information is based on TI's official datasheet and product documentation.
