Description and Introduction

Adjustable, Dual Output, Positive & Negative 1950-mA Switch Boost DC/DC 4x4 QFN-24 The TPS65131RGER 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:

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage:**  
  - Positive Output (VOUTP): Up to +15V  
  - Negative Output (VOUTN): Down to -15V  
- **Output Current:**  
  - Up to 250mA (positive rail)  
  - Up to 250mA (negative rail)  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin VQFN (RGER)  

### **Description:**  
The TPS65131RGER is a dual-output DC-DC converter designed to generate both positive and negative supply rails from a single input voltage. It integrates two boost converters (for positive and negative outputs) with low-noise charge pumps, making it suitable for applications requiring dual-rail power supplies, such as LCD bias, OLED displays, and precision analog circuits.

### **Features:**  
- **Dual Outputs:** Simultaneous positive and negative voltage generation.  
- **Integrated Charge Pump:** Reduces external component count.  
- **Low Noise:** Optimized for noise-sensitive applications.  
- **Adjustable Output Voltages:** Configurable via external resistors.  
- **Soft-Start:** Prevents inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Thermal Shutdown:** Protects the device from overheating.  

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