TPS60403 Description

Short technical summary and product information.

The TPS60403 from Texas Instruments is an unregulated charge pump voltage inverter designed to generate a negative output voltage from a positive input supply. It accepts an input voltage ranging from 1.6 V to 5.5 V, making it suitable for battery-powered applications using cells like NiCd, NiMH, alkaline, or Li-Ion. This device can provide a maximum output current of 60 mA.

Key features include the requirement of only three external 1-µF ceramic capacitors for a complete DC-DC charge pump inverter circuit. The TPS60403 operates at a fixed frequency of 250 kHz, contributing to its typical conversion efficiency of greater than 90% over a wide output current range. It also incorporates an integrated active Schottky diode for start-up into a load, reducing component count and board space.

Assembled in a compact 5-pin SOT-23 package, the TPS60403 is ideal for designs where board area is limited. Its typical quiescent current is 65 µA. Applications include LCD bias, sensor supply in portable instruments, and bipolar amplifier supply.

The device is designed for surface mount assembly. Its operating temperature range is from -40 °C to 125 °C.
