GENERAL DESCRIPTION
The TC1240/TC1240A is a doubling CMOS charge pump voltage converter in a small 6-Pin SOT-23A package. The TC1240 doubles an input voltage that can range from +2.5V to +4.0V, while Conversion efficiency is typically >99%. Internal oscillator frequency is 160 kHz for both devices. External component requirement is only two capacitors for standard voltage doubler applications. All other circuitry (including control, oscillator and power MOSFETs) are integrated on-chip. Typical supply current is 180 µA for the TC1240 and 550 µA for the TC1240A.
