Device Overview

Summary

The TC1240 is a doubling CMOS charge-pump voltage converter in a small 6-Pin SOT-23A package. TC1240 doubles an input voltage which can range from +2.5V to +4.0V. Conversion efficiency is typically >99%. Internal oscillator frequency is 160kHz for the TC1240. The TC1240 has an active high shutdown which limits the current consumption of the device to less than 1µA. External component requirement is only two capacitors for standard voltage doubler applications. All other circuitry, including control, oscillator, power MOSFETs are integrated on-chip. Typical supply current is 180µA and the device is available in a 6-Pin SOT-23A surface mount package.
