Description and Introduction

Single-Inductor, Triple-Output Supply for Small Form Factor TFT Display in QFN-16, Auto-Sequencing The TPS65123RGTR is a power management IC (PMIC) manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** TPS65123RGTR  
- **Package:** QFN-16 (3x3 mm)  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage 1 (Positive Charge Pump):** Adjustable up to 5.5V  
- **Output Voltage 2 (Negative Charge Pump):** Adjustable down to -5.5V  
- **Switching Frequency:** 1.2 MHz (typical)  
- **Output Current (Positive):** Up to 100 mA  
- **Output Current (Negative):** Up to 100 mA  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The TPS65123RGTR is a dual-output DC/DC converter that integrates a positive and negative charge pump to generate regulated output voltages. It is designed for applications requiring both positive and negative supply rails, such as LCD bias, OLED displays, and precision analog circuits. The device operates from a single input supply and provides two independently adjustable outputs.  

### **Features:**  
- **Dual Charge Pump Outputs:** Generates both positive and negative voltages.  
- **Adjustable Outputs:** Positive (up to +5.5V) and negative (down to -5.5V) via external resistors.  
- **Low Noise Operation:** Minimizes interference in sensitive applications.  
- **High Efficiency:** Up to 90% efficiency with optimized charge pump operation.  
- **Integrated Soft-Start:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Protects the device during low input voltage conditions.  
- **Thermal Shutdown:** Prevents damage from excessive heat.  
- **Small Footprint:** 16-pin QFN package (3x3 mm) for space-constrained designs.  

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