GENERAL DESCRIPTION
The TC828A is a CMOS “charge-pump” voltage con-
verter in an ultra-small 5-Pin SOT-23A package. It can invert
and/or double an input voltage that can range from +1.8V to
+5.5V. Conversion efficiency is typically >95%, and switch-
ing frequency is 12KHz.
The external component requirement is only two ca-
pacitors (10
F nominal) for standard voltage inverter appli-
cations.
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 38
A typically.
The TC828A is available in a 5-Pin SOT-23A surface
mount package.
