Features
General Description
•
•
•
•
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.

DETAILED DESCRIPTION
5.0
TYPICAL APPLICATIONS
The TC1240/TC1240A charge pump converter doubles the voltage applied to the VIN pin. Conversion consists of a two-phase operation (Figure 4-1). During the
first phase, switches S2 and S4 are open and S1 and S3
are closed. During this time, C1 charges to the voltage
on VIN and load current is supplied from C2. During the
second phase, S2 and S4 are closed, while S1 and S3
are open.
5.1
Output Voltage Considerations
During this second phase, C1 is level-shifted upward by
VIN volts. This connects C1 to the reservoir capacitor
C2, allowing energy to be delivered to the output as
needed. The actual voltage is slightly lower than 2 x VIN
since the four switches (S1-S4) have an on-resistance
and the load drains charge from reservoir capacitor C2.
VIN
S1
S2
TC1240/TC1240A
The TC1240/TC1240A performs voltage doubling but
does not provide regulation. The output voltage will
droop in a linear manner with respect to load current.
The value of this equivalent output resistance is approximately 12 nominal at +25°C and VIN = +5.0V for the
TC1240A and 17 nominal at +25°C and VIN = +2.8V
for the TC1240. VOUT is approximately +10.0V at light
loads for the TC1240A and +5.6V for the TC1240, and
droops according to the equation below:
EQUATION
V DROOP = I OUT  R OUT
V OUT = 2  VIN – V DROOP

TC1240/TC1240A
The switching frequency in Equation 5-1b is defined as
one-half the oscillator frequency (i.e., FSW = FOSC/2).
The 1/(FSW)(C1) term in Equation 5-1b is the effective
output resistance of an ideal switched capacitor circuit
(Figure 5-1 and Figure 5-2).
The output voltage ripple is given by Equation 5-2.
EQUATION 5-2:

V RIPPLE = -------------------------------- + 2  I OUT   ESR C2 

5.3
Capacitor Selection
In order to maintain the lowest output resistance and
output ripple voltage, it is recommended that low ESR
capacitors be used. Additionally, larger values of C1 will
lower the output resistance and larger values of C2 will
reduce output ripple (see Equation 5-1b).
Table 5-1 shows various values of C1 and the
corresponding output resistance values @ +25°C. It
assumes a 0.1 ESRC1 and 0.9 RSW. Table 5-2
shows the output voltage ripple for various values of
C2. The VRIPPLE values assume 5mA output load
current and 0.1 ESRC2.

Input Supply Bypassing
5.6
The VIN input should be capacitively bypassed to
reduce AC impedance and minimize noise effects due
to the switching internal to the device. The
recommended capacitor should be a large value (at
least equal to C1) connected from the input to GND.
5.5
Shutdown Input
Voltage Doubler
The most common application for charge pump
devices is the doubler (Figure 5-3). This application
uses two external capacitors – C1 and C2 (plus a power
supply bypass capacitor, if necessary). The output is
equal to 2 x VIN minus any voltage drops due to
loading. Refer to Table 5-1 and Table 5-2 for capacitor
selection.
The TC1240 and TC1240A are disabled when SHDN is
high, and enabled when SHDN is low. This input cannot
be allowed to float.

5.7
Cascading Devices
5.8
Two or more TC1240/TC1240As can be cascaded to
increase output voltage (Figure 5-4). If the output is
lightly loaded, it will be close to ((n + 1) x VIN), but will
droop at least by ROUT of the first device multiplied by
the IQ of the second. It can be seen that the output
resistance rises rapidly for multiple cascaded devices.
For the case of the two-stage ‘tripler’, output resistance
can be approximated as ROUT = 2 x ROUT1 + ROUT2,
where ROUT1 is the output resistance of the first stage
and ROUT2 is the output resistance of the second stage.
Paralleling Devices
To reduce the value of ROUT, multiple TC1240/
TC1240As can be connected in parallel (Figure 5-5).
The output resistance will be reduced by a factor of N,
where N is the number of TC1240/TC1240As. Each
device will require its own pump capacitor (C1x), but all
devices may share one reservoir capacitor (C2).
However, to preserve ripple performance, the value of
C2 should be scaled according to the number of
paralled TC1240/TC1240As, respectively.
5.9
Layout Considerations
As with any switching power supply circuit good layout
practice is recommended. Mount components as close
together as possible to minimize stray inductance and
capacitance. Also use a large ground plane to minimize
noise leakage into other circuitry.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
