TC1240 Datasheet (TelCom Semiconductor) - Positive Doubling Charge Pump

TC1240, Positive Doubling Charge Pump

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 w
