Quick Detail:


 Switched Capacitor Voltage Converters





The TCM828/829 are CMOS “charge-pump” voltage converters in ultra-small 5-Pin SOT-23A packages. They invert and/or double an input voltage which can range from +1.5V to +5.5V. Conversion efficiency is typically >95%.

Switching frequency is 12kHz for the TCM828 and 35kHz for the TCM829.

External component requirement is only two capacitors (3.3µF nominal) 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. Supply current is 50µA (TCM828) and 115µA (TCM829).

The TCM828 and TCM829 are available in a 5-Pin SOT-23A surface mount package.
