TC1221/TC1222
General Description
The TC1221/TC1222 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 +1.8V to +5.5V. Conversion efficiency is typically 96%. Switching frequency is 125kHz for the TC1221, 750kHz for the TC1222. When the s...
