Functional Description
The AHK3296 is an entry level driver IC, designed to
drive up to six white LEDs. The AHK3296 operates directly from a 2.7V to 5.5V power source and enables and
controls the current to the LEDs. LED current is individually controlled through integrated current sinks powered
from an external power supply. Low resistance and lowdrop out voltage current sinks allow the LEDs to operate
very close to the input supply voltage, eliminating the
need for an additional noisy boost power supplies.
The AHK3296 requires only one external component:
one 1μF ceramic input capacitor (CIN). The AHK3296 can
drive six constant output sinks (D1 to D6) each with a
maximum current of up to 20.6mA which is set internally. Skyworks S2Cwire serial interface enables the
AHK3296 and changes the current sink magnitudes for
main group (D1-D3) and sub group (D4-D6) through the
ENM and ENS pins respectively, thereby changing the
LED currents.
S2Cwire Serial Interface
The LED output current of the AHK3296 is controlled by
Skyworks S2Cwire serial interface. Since the LED current
is programmable, no PWM or additional control circuitry
is needed to control LED brightness. This feature greatly
reduces the burden on a microcontroller or system IC to
manage LED or display brightness, allowing the user to

DAC
“set it and forget it.” With its high-speed serial interface
(1MHz data rate), the LED current can be changed
quickly and easily. Also the non-pulsating LED current
reduces system noise and improves LED reliability. If
both the main (D1, D2 and D3) and sub (D4, D5 and D6)
groups are to be programmed with the same current
level per channel they can share a common GPIO microprocessor port.
The S2Cwire interface relies on the number of rising
edges to the ENS and ENM pins to set the registers. A
typical write protocol is a burst of ENM and ENS rising
edges, followed by a pause with ENM and ENS held high
for at least tLAT (500μs). The programmed current is then
seen at all current sink outputs. When ENM and ENS are
held low for an amount of time longer than tOFF (500μs),
the AHK3296 enters into shutdown mode and draws less
than 1μA from the input and the internal data register is
reset to zero.
The AHK3296 serial interface reduces the LED current on
each rising pulse of the enable inputs ENM and ENS. If the
AHK3296 is in shutdown, the first rising edge of the ENM
turns on all main channels D1-D3 to the maximum current level. The first rising edge of the ENS turns on all sub
channels D4-D6 to the maximum current level.. Successive
rising edges of ENM decrease the LED current for the
main channels (D1-D3) and successive rising edges of
ENS decrease the LED current for the sub channels (D4D6) as shown in Table 1 and Figure 1 for the AHK3296.

Table 1: AHK3296 LED Current Settings.
LED Selection
The AHK3296 is specifically intended for driving white
LEDs. However, the device design will allow the AHK3296
to drive most types of LEDs with forward voltage specifications typically ranging from 2.2V to 4.7V depending
upon supply voltage. LED applications may include
mixed arrangements for display backlighting, keypad
display, and any other application that needs a constant
current sink generated from a varying input voltage.
Since the D1 to D6 constant current sinks are matched
within 3% with negligible supply voltage dependence,
the constant current channels will be matched regardless
of the specific LED forward voltage (VF) levels. The low
dropout current sinks in the AHK3296 maximize performance and make it capable of driving LEDs with high
forward voltages. The six channels can be combined to
obtain a higher LED drive current without complication.
Shutdown
Code vs. LED Current
Since the current switches are the only power supplies
for all loads, there is no leakage current when all sink
switches are disabled. To activate the shutdown operation, both the ENM and ENS inputs for the AHK3296
should be strobed low for longer than tOFF (500μs). In
this state, the AHK3296 typically draws less than 1μA
from the input. All registers are reset to 0 in shutdown.

The current sinks of the AHK3296 can be combined to
drive higher current levels through the LEDs. As an
example, three LEDs can typically be driven at 61.8mA
each by combining the D1-D3 and D4-D6 outputs as
shown in Figure 3.

Capacitor Selection
Equivalent Series Resistance
Careful selection of the external capacitor CIN is important
because it will affect turn-on time and transient performance. Optimum performance will be obtained when low
equivalent series resistance (ESR) ceramic capacitor is
used; in general, low ESR may be defined as less than
100mΩ. A value of 1μF for the input capacitor is a good
starting point when choosing a capacitor. If the constant
current sinks are only programmed for light current levels
then the input capacitor size may be decreased.
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.
Capacitor Characteristics
Ceramic composition capacitor is highly recommended
over all other types of capacitors for use with the
AHK3296. Ceramic capacitors offer many advantages
over their tantalum and aluminum electrolytic counterparts. A ceramic capacitor typically has very low ESR, is
lower cost, has a smaller PCB footprint, and is non polarized. Since ceramic capacitors are non-polarized, they
are not prone to incorrect connection damage.
10
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., larger than 2.2μF) are
often available in low cost Y5V and Z5U dielectrics, but
capacitors larger than 1μF are not typically required for
AHK3296 applications.

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

Table 2 indicates the function of each button or button
combination. To power-on the evaluation board, connect
a power supply or battery to the DC- and DC+ terminals.
A red LED indicates that power is applied. The evaluation
board is made flexible so that the user can disconnect
the enable line from the microcontroller and apply external enable signal. External enable signal must be applied
to the EN pin.
The user interface for the AHK3296 evaluation board is
provided by three buttons and two connection terminals.
The board is operated by supplying external power and
pressing individual buttons or button combinations.
When applying external enable signal, consideration
must be given to the voltage levels. The externally
applied voltage should not exceed the supply voltage
that is applied to the IN pins of the device (DC+).
