Description
Switched Capacitor Voltage Converters with Shutdown in SOT Packages .
The TC1219/TC1220 are CMOS “charge-pump” voltage converters in ultra-small 6-Pin SOT-23A packages.
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
Applications
* With a few additional components a positive doubler can also be built. All other circuitry, including control, oscillator, power MOSFETs are integrated on-chip. Typical supply currents are 60µA (TC1219), 115µA (TC1220). All devices are available in 6-pin SOT-23A surface mount packages. Application
