Description
The TPS60401DBVR is a charge pump voltage inverter from Texas Instruments. It is designed to generate a negative output voltage from a positive input voltage, making it suitable for applications requiring bipolar power supplies. Operating over an input voltage range of 1.6V to 5.5V, it provides an inverted output voltage at a fixed gain of -1.
The TPS60401 is compact and efficient, making it ideal for battery-powered devices and space-constrained applications. It features a low quiescent current of typically 65 µA and a shutdown current of less than 1 µA, conserving power when the device is not in use. The device operates at a fixed frequency of 250 kHz, reducing noise and the need for large external components.
Packaged in a small SOT-23-5, the TPS60401DBVR integrates well into compact designs. It requires only a few external components, typically two capacitors, to function, simplifying design and reducing cost. Common applications include operational amplifier power supplies, LCD biasing, and sensor interfaces.
