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.
External component requirement is only two capacitors
(3.3 F
nominal)
for
standard
voltage
inverter
applications. With a few additional components, a
positive doubler can also be built. All other circuitry,
including control, oscillator and power MOSFETs, are
integrated on-chip. Supply current is 50 A (TCM828)
and 115 A (TCM829).
The TCM828 and TCM829 devices are available in a
5-Pin SOT-23 surface mount package.
