TC1219 - Switched Capacitor Voltage Converters
The TC1219/TC1220 are CMOS “charge-pump” voltage converters in ultra-small 6-Pin SOT-23A packages.
They invert and/or double an input voltage which can range from +2.5V to +5.5V.
Conversion efficiency is typically >95%.
Switching frequency is 12kHz for the TC1219, 35kHz for the TC1220.
