* Charge Pumps in 6-Pin SOT-23A Package >95% Voltage Conversion Efficiency Voltage Inversion and/or Doubling Operates .
With a few additional components a positive doubler can also be built. All other circuitry, including control, oscillat.
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 f.
