The TPS60403DBVR from Texas Instruments is an unregulated charge pump voltage inverter designed for efficient power management. It operates with an input voltage range from 1.6V to 5.5V and can deliver up to 60mA of output current. This device is suitable for applications requiring a negative voltage rail from a positive supply.
Key electrical characteristics include a fixed output voltage capability and a switching frequency of 250kHz. The device features a ratiometric function and does not utilize synchronous rectification. Its typical quiescent current is very low at 40µA, contributing to improved efficiency, especially at low output currents.
Packaged in a compact SOT-23-5 surface-mount package, the TPS60403DBVR is designed for space-constrained applications. It operates within an ambient temperature range of -40°C to 125°C, making it suitable for a wide variety of environmental conditions. Only three small 1µF ceramic capacitors are needed to build a complete DC-DC charge pump inverter circuit.
