TC1222 - High Frequency Switched Capacitor Voltage Converters

Download the TC1222 datasheet PDF. This datasheet also covers the TC1221 variant, as both devices belong to the same high frequency switched capacitor voltage converters family and are provided as variant models within a single manufacturer datasheet.

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%.

M Features • • • • • • • • 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 shutdown pin is held at a logic low, the device goes into a very low power mode of operation, consuming less than 1µA of supply current. For standard voltage inverter applications, the device requires only two external capacitors. With a few additional components a positive doubler can also be built. All other circuitry, including control, oscillator, power MOSFETs are integrated on-chip.
