Description and Introduction

4-CH LCD Bias w/ Fully Int. Pos. Charge Pump, 3.3V LDO Controller & 1.6A Min. Boost Ilim 24-VQFN -40 to 85 The TPS65141RGER is a power management IC (PMIC) manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage 1 (Positive Charge Pump):** Adjustable from 5V to 6.3V  
- **Output Voltage 2 (Negative Charge Pump):** Adjustable from -5V to -6.3V  
- **Output Current (Positive):** Up to 100mA  
- **Output Current (Negative):** Up to 100mA  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin VQFN (RGER)  

### **Description:**  
The TPS65141RGER is a dual-output DC-DC converter designed to generate both positive and negative supply voltages from a single input. It integrates two regulated charge pumps, providing stable ±5V to ±6.3V outputs, making it suitable for applications requiring dual-rail power supplies, such as LCD bias, OLED displays, and audio amplifiers.

### **Features:**  
- **Dual Charge Pump Outputs:** Generates both positive and negative voltages.  
- **Adjustable Output Voltages:** Configurable via external resistors.  
- **Low Noise Operation:** Minimizes output ripple.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Protects the IC during low input voltage conditions.  
- **Thermal Shutdown:** Prevents overheating damage.  
- **Small Footprint:** 24-pin VQFN package (4mm × 4mm).  

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