The TC1240/TC1240A is a doubling CMOS charge
pump voltage converter in a small 6-Pin SOT-23A
package. The TC1240 doubles an input voltage that
can range from +2.5V to +4.0V, while the TC1240A
doubles an input voltage that can range from +2.5V to
+5.5V. Conversion efficiency is typically >99%. Internal
oscillator frequency is 160 kHz for both devices. The
TC1240 and TC1240A have an active-high shutdown
that limits the current consumption of the devices to
less than 1 μA.
External component requirement is only two capacitors
for standard voltage doubler applications. All other
circuitry (including control, oscillator and power
MOSFETs) are integrated on-chip. Typical supply current
is 180 μA for the TC1240 and 550 μA for the
TC1240A. Both devices are available in a 6-Pin SOT-
23A surface mount package.
