Description and Introduction

60mA Charge Pump Voltage Inverter with Fixed 250kHz Operation The TPS60403 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 Options:** SOT-23 (5-pin), SC-70 (5-pin)  

### **Descriptions:**  
The TPS60403 is a low-power, unregulated charge pump voltage inverter that generates a negative output voltage from a positive input supply. It is designed for applications requiring a simple and efficient inverting power supply.  

### **Features:**  
- **No Inductors Required** – Uses only flying capacitors  
- **Low Quiescent Current:** 65µA (typical)  
- **Automatic Power-Save Mode** for improved efficiency at light loads  
- **Short-Circuit Protection**  
- **Low Output Impedance**  
- **Small Footprint** with minimal external components  

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