TC1219 - Switched Capacitor Voltage Converters

General Description

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%.

Key Features

  • Charge Pumps in 6-Pin SOT-23A Package >95% Voltage Conversion Efficiency Voltage Inversion and/or Doubling Operates from +2.5V to +5.5V Up to 25mA Output Current Only Two External Capacitors Required Low Power Consumption Power-Saving Shutdown Mode TC1220 Compatible with 1.8V Logic Systems M TC1219/TC1220 General.
