Description and Introduction

4-CH LCD Bias w/ Fully Int. Positive Charge Pump, LDO Controller, HVS (VDD / VGH) & Temp. Sensor The TPS65167A is a power management IC (PMIC) manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltages:**  
  - Positive Output: Up to +15V  
  - Negative Output: Down to -15V  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin VQFN (4mm x 4mm)  

### **Descriptions:**  
The TPS65167A is a highly integrated power management IC designed for applications requiring both positive and negative voltage rails. It combines a step-up (boost) converter for the positive output and an inverting buck-boost converter for the negative output. The device is optimized for low-noise operation, making it suitable for precision analog circuits, LCD bias supplies, and other applications requiring dual-rail power.

### **Features:**  
- **Dual-Output Power Supply:** Generates both positive and negative voltages from a single input.  
- **Low Noise:** Optimized for sensitive analog applications.  
- **Integrated Synchronous Rectifiers:** Improves efficiency and reduces external component count.  
- **Soft-Start & Short-Circuit Protection:** Enhances reliability.  
- **Adjustable Output Voltages:** Configurable via external resistors.  
- **Low Quiescent Current:** Improves power efficiency in standby modes.  
- **I²C Programmable (Optional):** Some variants support digital control.  

This information is strictly factual and sourced from TI's official documentation.
