TC1220 General Description

The TC1219/1220 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 12 KHz for the TC1219, 35 KHz for the TC1220. When the shutdown pin is held at a logic low, the device goes into a very low power mode of operation, consuming less than 1 µA of supply current. External component requirement is only two capacitors for standard voltage inverter 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 60 µA (TC1219), 115 µA (TC1220). All devices are available in 6-pin SOT-23A surface mount packages.

Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These
are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operation sections of the specifications is not implied. Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability.
