Description and Introduction

60mA Charge Pump Voltage Inverter with Fixed 50kHz Operation 5-SOT-23 -40 to 85 The TPS60402DBVRG4 is a charge pump voltage inverter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 1.6V to 5.5V  
- **Output Voltage:** -1.6V to -5.5V (inverts input voltage)  
- **Output Current:** Up to 60mA  
- **Switching Frequency:** 250kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
The TPS60402DBVRG4 is a low-power, unregulated charge pump voltage inverter. It generates a negative output voltage from a positive input supply without requiring inductors. It is designed for low-noise applications and provides a simple, compact solution for generating negative voltages.  

### **Features:**  
- **No Inductors Required** – Uses only flying capacitors  
- **Low Quiescent Current:** 65µA (typical)  
- **Low Output Impedance:** 17Ω (typical)  
- **Automatic Power-Save Mode** for light loads  
- **Short-Circuit Protection**  
- **Small Footprint** – SOT-23-5 package  

This device is commonly used in LCD bias, sensor supplies, and other applications requiring a negative voltage rail.
