... OUT GND © 2010 Microchip Technology Inc. TCM828/TCM829 Description The TCM828/TCM829 devices are CMOS “charge- pump” voltage converters in ultra-small, 5-Pin SOT-23 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 12 kHz for the TCM828, and 35 kHz for the TCM829 ...
