... C TCM828 TCM829 OUT GND © 2001 Microchip Technology Inc. DS21488A GENERAL DESCRIPTION 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%. ...
