The TC1240AECHTR is a doubling CMOS charge Pump Voltage Converter for battery powered devices, PDAs and portable data loggers. The TC1240A doubles an input voltage that can range from +2.5 to +5.5V. Conversion efficiency is typically 99%. Internal oscillator frequency is 160kHz for both devices. The TC1240A have an active-high shutdown that limits the current consumption of the devices to less than 1µA. 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.
