Description and Introduction

3-CH LCD Bias w/ GPM, VCOM Buffer & Gate Driver for Isolation Switch The TPS65150 is a power management IC manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltages:**  
  - Positive Output: Up to +15V  
  - Negative Output: Down to -15V  
- **Output Current:** Up to 250mA (positive and negative rails)  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin QFN (4mm x 4mm)  

### **Descriptions:**  
The TPS65150 is a compact, high-efficiency power supply IC designed to generate both positive and negative output voltages from a single input supply. It integrates two step-up (boost) converters and an inverting buck-boost converter to provide dual-rail outputs, making it suitable for applications requiring bipolar supplies such as LCD displays, OLED panels, and operational amplifiers.  

### **Features:**  
- **Integrated Dual-Output Power Supply:** Generates both positive and negative voltages.  
- **Synchronous Rectification:** Improves efficiency and reduces external component count.  
- **Adjustable Output Voltages:** Configurable via external resistors.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Thermal Shutdown Protection:** Safeguards the IC from overheating.  
- **Low Quiescent Current:** Optimized for battery-powered applications.  

This IC is commonly used in portable electronics, industrial systems, and display technologies requiring stable dual-rail power supplies.
