TC1240ECHTR

The TC1240ECHTR is a positive CMOS doubling charge-pump Voltage Converter with shutdown. The TC1240 doubles an input voltage that can range from 2.5 to 4V. Conversion efficiency is typically <gt/>99%. Internal oscillator frequency is 160kHz for this device. The TC1240 has 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 are integrated on-chip. Typical supply current is 180µA for the TC1240.

• Conversion consists of a 2-phase operation
• Doubles the voltage applied to the VIN pin
• Power-saving shutdown mode
• <gt/>99% Voltage conversion efficiency
• Shutdown input fully compatible with 1.8V logic systems
