AAT3113, AAT3114/14A
High Efficiency 1.5X Fractional Charge
Pumps For White LED Applications
General Description
Features
The AAT3113 and AAT3114/14A are low noise, constant frequency charge pump DC/DC converters
that use fractional (1.5X) conversion to increase efficiency in white LED applications. The devices can
be used to produce current levels up to 20mA for
each output from a 2.7V to 5.5V input. A low external parts count (two 1µF flying capacitors and two
small bypass capacitors at VIN and OUT) makes
these devices ideally suited for small, battery-powered applications.

AnalogicTech’s Simple Serial Control™ (S2Cwire™)
interface is used to enable, disable, and set the
LED drive current for 32-level logarithmic scale LED
brightness control. AAT3113 and AAT3114/14A
devices have a thermal management system for
protection in the event of a short-circuit condition on
any of the output pins. Built-in soft-start circuitry
prevents excessive inrush current during start-up.
A high switching frequency enables the use of small
external capacitors. A low-current shutdown feature
disconnects the load from VIN and reduces quiescent current to less than 1µA. The AAT3113 provides four LED current source outputs, and the
AAT3114/14A provides six. The AAT3113 is available in a Pb-free 12-pin TSOPJW package, and the
AAT3114/14A is available in a Pb-free 16-pin QFN
package.

Functional Description
The AAT3113 and AAT3114/14A devices are high
efficiency 1.5X fractional charge pumps intended
for white LED backlight applications. The fractional charge pump consists of a linear regulator followed by a 1.5X charge pump. The AAT3113 and
AAT3114/14A require only four external components: two 1µF ceramic capacitors for the charge
pump flying capacitors (C1 and C2), one 1µF
ceramic capacitor for CIN, and one 0.33µF to 1µF
ceramic capacitor for COUT. The charge pump output is converted into four or six constant current
outputs (D1 to D4 or D6) to drive four or six individual LEDs with a maximum of 20mA each. The
current source output magnitude is controlled by
the EN/SET serial data S2Cwire interface. The
interface records rising edges of the EN/SET pin

and decodes them into 32 individual current level
settings each 1dB apart (see Table 1, Current
Level Settings). Code 32 is full scale, and Code 1
is full scale attenuated by 31dB. The modulo 32
interface wraps states back to state 1 after the
32nd clock. With each EN/SET pulse, the output
current increases by 1dB. To decrease the output
current by 1dB, 31 EN/SET clock pulses are
required. The counter can be clocked at speeds up
to 1MHz, so intermediate states are not visible.
The first rising edge of EN/SET enables the IC and
initially sets the output LED current to -31dB, the
lowest setting equal to 525µA. Once the final clock
cycle is input for the desired brightness level, the
EN/SET pin is held high to maintain the device output current at the programmed level. The device is
disabled 500µs after the EN/SET pin transitions to
a logic low state.

high to maintain the device output current at the
programmed level. The device is disabled 500µs
after the EN/SET pin transitions to a logic low state.
The current source output magnitude is controlled
by the EN/SET pin using AnalogicTech’s Simple
Serial Control (S2Cwire) interface. The interface
records rising edges of the EN/SET pin and
decodes them into 32 individual current level settings each 1dB apart. Code 32 is full scale, and
Code 1 is full scale attenuated by 31dB. The modulo 32 interface wraps states back to state 1 after
the 32nd clock, so 1dB of attenuation is achieved by
clocking the EN/SET pin 31 times (see graph titled,
“IDIODE Response -9dB to -10dB”). The counter can
be clocked at speeds up to 1MHz, so intermediate
states are not visible. The first rising edge of
EN/SET enables the IC and initially sets the output
LED current to -31dB, the lowest setting equal to
525µA. Once the final clock cycle is input for the
desired brightness level, the EN/SET pin is held
The EN/SET timing is designed to accommodate a
wide range of data rates. After the first rising edge
of EN/SET, the charge pump is enabled and reaches full capacity after the soft-start time (TSS).
During the soft-start time, multiple clock pulses
may be entered on the EN/SET pin to set the final
output current level with a single burst of clocks.
Alternatively, the EN/SET clock pulses may be
entered one at a time to gradually increase the
LED brightness over any desired time period. A
constant current is sourced as long as EN/SET
remains in a logic high state. The current source
outputs are switched off after EN/SET has
remained in a low state for at least the tOFF timeout
period (see Figure 1).

LED Selection
AAT3113 and AAT3114/14A devices are designed
to drive white LEDs with forward voltages to 4.2V.
Since the D1:D6 output current sources are
matched with negligible voltage dependence, the
LED brightness will be matched regardless of their
forward voltage matching.
Charge Pump Efficiency
The AAT3113 and AAT3114/14A devices are fractional charge pumps. The efficiency (η) can be simply defined as a linear voltage regulator with an
effective output voltage that is equal to one and one
half times the input voltage. Efficiency (η) for an
ideal 1.5X charge pump can typically be expressed
as the output power divided by the input power:
η=
10
POUT
PIN
In addition, with an ideal 1.5X charge pump, the
output current may be expressed as 2/3 of the
input current. The expression to define the ideal
efficiency (η) can be rewritten as:
η=
VOUT · IOUT
V
POUT
=
= OUT
PIN
VIN · 1.5IOUT 1.5VIN
-or-
η(%) = 100
⎛ VOUT ⎞
⎝ 1.5VIN⎠
For a charge pump with an output of 5 volts and a
nominal input of 3.5 volts, the theoretical efficiency
is 95%. Due to internal switching losses and IC
quiescent current consumption, the actual efficiency can be measured at 93%. These figures are in
close agreement for output load conditions from
1mA to 100mA. Efficiency will decrease as load

current drops below 0.05mA or when the level of
VIN approaches VOUT. Refer to the Typical
Characteristics section of this datasheet for measured plots of efficiency versus input voltage and
output load current for the given charge pump output voltage options.
Power Efficiency and Device Evaluation
The charge pump efficiency discussion in the previous section only accounts for efficiency of the
charge pump section itself. Due to the unique circuit architecture and design of the AAT3113 and
AAT3114/14A, it is very difficult to measure efficiency in terms of a percent value comparing input
power over output power. Since the device outputs
are pure constant current sources, it is difficult to
measure the output voltage for a given output (D1
to D6) to derive an output power measurement. For
any given application, white LED forward voltage
levels can differ, yet the output drive current will be
maintained as a constant. This makes quantifying
output power a difficult task when taken in the context of comparing to other white LED driver circuit
topologies. A better way to quantify total device efficiency is to observe the total input power to the
device for a given LED current drive level. The best
white LED driver for a given application should be
based on trade-offs of size, external components
count, reliability, operating range, and total energy
usage...not just "% efficiency."

Capacitor Selection
Careful selection of the four external capacitors
CIN, C1, C2, and COUT is important because they will
affect turn-on time, output ripple, and transient per3113.2006.07.1.9
Capacitor Characteristics
Ceramic composition capacitors are highly recommended over all other types of capacitors for use
with the AAT3113 and AAT3114/14A products.
Ceramic capacitors offer many advantages over
their tantalum and aluminum electrolytic counterparts. A ceramic capacitor typically has very low
ESR, is lowest cost, has a smaller PCB footprint,
and is non-polarized. Low ESR ceramic capacitors
help maximize charge pump transient response.
Since ceramic capacitors are non-polarized, they
are not prone to incorrect connection damage.
Equivalent Series Resistance: ESR is an important characteristic to consider when selecting a
capacitor. ESR is a resistance internal to a capacitor that is caused by the leads, internal connections, size or area, material composition, and ambient temperature. Capacitor ESR is typically measured in milliohms for ceramic capacitors and can
range to more than several ohms for tantalum or
aluminum electrolytic capacitors.
Ceramic Capacitor Materials: Ceramic capacitors
less than 0.1µF are typically made from NPO or
C0G materials. NPO and C0G materials generally
have tight tolerance and are very stable over temperature. Larger capacitor values are usually composed of X7R, X5R, Z5U, or Y5V dielectric materials. Large ceramic capacitors (i.e., greater than
2.2µF) are often available in low-cost Y5V and Z5U
dielectrics, but capacitors greater than 1µF are not
typically required for AAT3113 or AAT3114/14A
applications.

formance. Optimum performance will be obtained
when low equivalent series resistance (ESR)
ceramic capacitors are used. In general, low ESR
may be defined as less than 100mΩ. A value of
1µF for all four capacitors is a good starting point
when choosing capacitors. If the LED current
sources are only programmed for minimal current
levels, then the capacitor size may be decreased.
Capacitor area is another contributor to ESR.
Capacitors that are physically large will have a lower
ESR when compared to an equivalent material
smaller capacitor. These larger devices can improve
circuit transient response when compared to an
equal value capacitor in a smaller package size.

Thermal Protection
Each channel of the output is equipped with a test

small (~2µA) current source injected into each output pin to detect the presence of an LED. Unused
channels that are tied to ground or LED load fail
short will be automatically diasbled instead of wasting the programmed output current. The test current
in the AAT3114A is higher (~150µA) to accommodate LEDs with lower impedance in failure mode.
The AAT3113 and AAT3114/14A have a thermal
protection circuit that will shut down the charge
pump and current outputs if the die temperature
rises above the thermal limit. However, thermal
resistance of the QFN package is so low that if, in
the case of the AAT3114/14A, all six outputs are
shorted to ground at maximum 20mA output level,
the die temperature will not rise sufficiently to trip
the thermal protection. The thermal protection will
only trip if COUT is shorted to ground and the ambient temperature is high.

High Efficiency 1.5X Fractional Charge
Pumps For White LED Applications
Driving white LED display module backlights
and individual white LEDs connected in parallel:
current sources. This feature is particularly useful
to power pre-manufactured display modules that are
pre-wired with white LED backlights connected in a
parallel circuit configuration. All outputs can be connected in parallel to drive groups of LEDs as well.
The internal current source reference circuit bases
feedback from current sensed on the D1 output. For
best operation, the only requirement for this application is that the output D1 should always be connected to the load circuit.
The AAT3114/14A D1 to D6 outputs are true constant current sources capable of driving up to 20mA
each over the operation input voltage range. Since
these outputs are true constant current sources,
they may be connected in parallel to drive a single
power output. Any combination of outputs (D1 to
D6) may be connected in parallel. The maximum
total output current is a sum of parallel-connected
