TC1240AECHTR by Microchip Technology

Positive Doubling Charge Pump with Shutdown
Features
>99% Typical Voltage Conversion Efficiency
Voltage Doubling
Low Output Resistance (12Ohms Typical)
Only Two External Capacitors Required
Consumes 550u00b5A (Typical) in Active Mode
Power-Saving Shutdown Mode (1u00b5A Maximum)
Shutdown Input Fully Compatible with 1.8V Logic Sytems
Description
The TC1240A is a doubling CMOS charge-pump voltage converter in a small 6-Pin SOT-23A package. TC1240A doubles an input voltage which can range from +2.5V to +5.5V. Conversion efficiency is typically >99%. Internal oscillator frequency is 160kHz for the TC1240A. The TC1240A 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 550µA and the device is available in a 6-Pin SOT-23A surface mount package.
