High Frequency Switched Capacitor Voltage Converters
with Shutdown in SOT Packages
Features
General Description
• Charge Pumps in 6-Pin SOT-23A Package
• 96% Voltage Conversion Efficiency
• Voltage Inversion and/or Doubling
• Operates from +1.8V to +5.5V
The TC1221/TC1222 are CMOS “charge-pump”
voltage converters in ultra-small 6-Pin SOT-23A
packages. They invert and/or double an input voltage
which can range from +1.8V to +5.5V. Conversion
efficiency is typically 96%. Switching frequency is
125kHz for the TC1221, 750kHz for the TC1222. When
the shutdown pin is held at a logic low, the device goes
into a very low power mode of operation, consuming
less than 1µA of supply current.
• Up to 25mA Output Current
• Only Two External Capacitors Required
• Power-Saving Shutdown Mode
• Fully Compatible with 1.8V Logic Systems
For standard voltage inverter applications, the device
requires only two external capacitors. With a few
additional components a positive doubler can also be
built. All other circuitry, including control, oscillator,
power MOSFETs are integrated on-chip. Typical supply
currents are 290µA (TC1221) and 1800µA (TC1222).
Applications
• LCD Panel Bias
• Cellular Phones
• Pagers
• PDAs, Portable Data Loggers
• Battery-Powered Devices
All devices are available in 6-pin SOT-23A surface
mount packages.

DETAILED DESCRIPTION
The TC1221/TC1222 charge pump converters invert
the voltage applied to the VIN pin. Conversion consists
of a two-phase operation (Figure 3-1). During the first
phase, switches S2 and S4 are opened 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, and S1 and S3
are opened. This action connects C1 across C2,
restoring charge to C2.

The TC1221/TC1222 perform voltage conversion but
do 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 approxi-
mately 25Ω nominal at +25°C and VIN = +5V. VOUT is
approximately -5V at light loads, and droops according
to the equation below:

Charge Pump Efficiency
The overall power efficiency of the charge pump is
affected by four factors:
R
C1
C2
L
1. Losses from power consumed by the internal
oscillator, switch drive, etc. (which vary with
input voltage, temperature and oscillator
frequency).
2. I2R losses due to the on-resistance of the
MOSFET switches on-board the charge pump.

4. Losses that occur during charge transfer (from

Most of the conversion losses are due to factors (2) and
(3) above. These losses are given by Equation 4-1(b).

Capacitor Selection
EQUATION 4-1:
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. (Equation 4-1(b) and
Equation 4-3).

C
The 1/(fOSC)(C1) term in Equation 4-1(b) is the
effective output resistance of an ideal switched
capacitor circuit (Figure 4-1 and Figure 4-2). The value
of RSWITCH can be approximated at 0.5Ω for the
TC1221/TC1222.
The remaining losses in the circuit are due to factor (4)
above, and are shown in Equation 4-2. The output
voltage ripple is given by Equation 4-3.

Table 4-1 shows various values of C1 and the
corresponding output resistance values @ +25°C. It
assumes a 0.1Ω ESRC1 and 2Ω RSWITCH. Table 4-2
shows the output voltage ripple for various values of
C2. The VRIPPLE values assume 10mA output load

Shutdown Input
The TC1221/TC1222 is enabled when SHDN is high,
and disabled when SHDN is low. This input cannot be
allowed to float. The SHDN input should be limited to
0.5V above VIN to avoid significant current flows.

The most common application for charge pump
devices is the inverter (Figure 4-3). This application
uses two external capacitors: C1 and C2 (plus a power
supply bypass capacitor, if necessary). The output is
equal to -VIN plus any voltage drops due to loading.

selection.

Cascading Devices
4.8
Paralleling Devices
Two or more TC1221/TC1222 can be cascaded to
increase output voltage (Figure 4-4). If the output is
lightly loaded, it will be close to (-2 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.
To reduce the value of ROUT, multiple TC1221/
TC1222’s can be connected in parallel (Figure 4-5).
The output resistance will be reduced by a factor of N
where N is the number of TC1221/TC1222. Each
device will require its own pump capacitor (C1), 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
paralleled TC1221/TC1222.

Voltage Doubler/Inverter
4.10 Diode Protection for Heavy Loads
Another common application of the TC1221/TC1222 is
shown in Figure 4-6. This circuit performs two functions
in combination. C1 and C2 form the standard inverter
circuit described above. C3 and C4 plus the two diodes
form the voltage doubler circuit. C1 and C3 are the
pump capacitors and C2 and C4 are the reservoir
capacitors. Because both sub-circuits rely on the same
switches if either output is loaded, both will droop
toward GND. Make sure that the total current drawn
from both the outputs does not total more than 40mA.
When heavy loads require the OUT pin to sink large
currents being delivered by a positive source, diode
protection may be needed. The OUT pin should not be
allowed to be pulled above ground. This is
accomplished by connecting
(1N5817) as shown in Figure 4-7.

Schottky diode
4.11 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. Noise leakage into other circuitry can be
minimized with the use of a large ground plane.
