DESCRIPTION
The SP6683 is a high power current regulated charge pump ideal for converting a Li-Ion
battery input for driving up to 8 white LED’s used in backlighting color displays. The SP6683
operates with an internal 1.2MHz clock, enabling the use of small external components.
Output current can be accurately regulated by modulating the switcher between the charge
pump and output capacitor. In shutdown mode, the SP6683 discharges the output to ground
and draws less than 500nA current. Offered in 10-pin DFN package, the SP6683 family
includes three options that allow the user to optimize LED driving circuit; SP6683-LV with low
voltage reference, SP6683-03 with high impedance output in shutdown, and SP6683 with
pulled down output in shutdown.

THEORY OF OPERATION
General Overview
The SP6683 is a current regulated charge pump
ideal for converting a Li-Ion battery input for
driving white LEDs used in camera flash or
backlighting color displays in cellular phones,
PDAs, digital cameras and MP3 players. The
SP6683 is able to efficiently drive one 200mA
Flash LED or up to eight 20mA white LEDs in
parallel and maintain a constant brightness over
a very wide operating voltage range (2.7V to
5.5V). The SP6683 operates with an internal
1.2MHz clock, enabling the use of small external components. Other features of SP6683 include PWM dimming control as well as complete input/output disconnect in shutdown. In
shutdown mode the IC typically draws 500nA
current. The output regulation is achieved by
sensing the voltage at the feedback pin and
modulating the switch between the charge pump
and output capacitor.
1) Voltage Reference. This block provides the
315mV and 1.25V reference voltages needed
for the two comparators.
2) Mode Control. An external voltage divider
connected to the VMODE pin will define an input
voltage to the mode comparator which sets the
logic state of the mode selection outputs to the
X1 or X1.5 modes. VMODE is compared to a
1.25V bandgap voltage. For example, if one
makes a 158K/100K divider, the mode will
change at 2.58 x 1.25 V = 3.23V. A comparatorbased cycle by cycle regulation ensures that no
mode change occurs during cycles.
3) Clock Manager. An internal 1.2MHz clock
is generated in this block. Depending on the
mode control, the appropriate clock phasing is
generated here and sent to the startup and charge
pump switches block.
4) VOUT Comparator & Output Control. A
315mV reference voltage is compared to feedback voltage to control the VOUT needed for the
application. Output current is set by a bias
resistor from the FB pin to the GND pin chosen
by the relationship:
IOUT = VFB
RFB
Theory of Operation
The SP6683 regulated charge pump block diagram consists of four main blocks (Voltage
Reference, Mode Control, Clock Manager, Startup and Charge-Pump Switches) and two comparators (VMODE Comparator and VOUT Comparator).

APPLICATION INFORMATION

Anode
The white LED load configuration used by
customers can be discrete white LEDs or a white
LED module. Inside the white LED module,
there may or may not be resistors in series with
the white LEDs. According to the different
application requirements, the SP6683 can be
configured as either a voltage source or a current
source to provide solutions for these different
applications, as shown below. The figure shows
the SP6683 driving discrete white LEDs as a
current source.

Driving discrete white LEDs as current source
The current in one white LED current is set by
the ratio of the feedback pin voltage (315mV)
and the bias resistor RB. To set the operating
current, RB can be selected by:
Driving 2-wire white LED module as current source
In the figure above, the SP6683 was used to
drive a 2-wire white LED module (without
internal series resistors) as a current source. The
bias resistor RB is selected to regulate the total
current of the white LED module instead of the
current of a single LED as in the figure showing
the 3 wire white LED module.
RB = VFB

The current of the remaining white LEDs is set
according to the similarity of the white LEDs.
3-wire white LED modules with internal series
resistors (as shown in figure below) can also be
driven in this way.

APPLICATION INFORMATION
The SP6683-03ER has the discharge MOSFET
disabled ensuring that the output node is at high
impedance during shutdown. This can be useful
if the system is feeding LED current from another source while the SP6683 is in shutdown.
In this application, the bias resistor can be selected by:
R = VFB
B
ILED (TOTAL)
where ILED(TOTAL) is the total operating current
of all the white LEDs.
The SP6683-LV offers a lower reference voltage that allows to reduce efficiency loss occurring in the current sense resistor. This part is
ideal for driving single LEDs for Flash applications.
To use SP6683 as a voltage source for fixed
voltage applications, a voltage divider is need to
program the output voltage, as shown in the figure
above. The output voltage is set by the ratio of
the two resistors and the feedback control voltage as shown by:
Reducing Component Count
It is possible to reduce the number of external
components by shorting pins 2 & 9 and omitting
the flying capacitor. In this mode, the charge
pump operates in a "quasi" doubler mode. This
reduces efficiency but does allow for one less
external capacitor. This circuit is recommended
only when Input and Output Voltages have
similar range, which is very common when
driving white LEDs from a Li-Io battery.
VOUT = ( 1 + R5 ) • VFB
R6
Brightness Control Using PWM
Dimming control can be achieved by applying a
PWM control signal to the EN/PWM pin. The
brightness of the white LEDs is controlled by
increasing and decreasing the duty cycle of the
PWM signal. While operating frequency range
is from 60Hz to 700Hz, the recommended maximum brightness frequency range is from 60Hz
to 200Hz. A repetition rate of at least 60Hz is
required to prevent flicker.

Three Options for Optimization
The SP6683 family includes three options that
allow the user to optimize the LED driving
circuit. The SP6683 includes an on-board discharge switch that ensures that VOUT is completely discharged in shutdown. This feature is
very useful in systems using PWM dimming,
when the SP6683 is periodically turned on and
off. The discharge switch ensures that the falling and rising edges of the LED current have
similar durations.

APPLICATION INFORMATION
Component Selection
The guideline for selecting divider resistors is as
follows. For high input voltage, the SP6683 will
work in X1 mode. When the input voltage drops
to VTH threshold voltage, it will switch to X1.5
mode automatically. The VTH threshold voltage
for mode change can be calculated by:
Ceramic capacitors are recommended for their
inherently low ESR, which will help produce
low peak-to-peak output ripple, and reduce high
frequency spikes.
The fly capacitor controls the strength of the
charge pump. Selection of the fly capacitor is a
tradeoff between the output voltage ripple and
the output current capability. Decreasing the fly
capacitor will reduce the output voltage ripple
because less charge will be delivered to the
output capacitor. However, a smaller fly capacitor leads to larger output resistance, thus decreasing the output current capability and the
efficiency of the circuit. Increasing the value of
the input and output capacitors could further
reduce the input and output ripple. For backlighting applications up to 80mA output current,
CIN = COUT = 1µF is typically used. For applications with more than 80mA output current, for
example in Flash applications where Iout can be
as much as 200mA, CIN = COUT = 2.2µF is
recommended. For peak performance, place all
capacitors as close to the SP6683 as possible.
VTH = (VF + 0.315 + m • ILED • ROUT)
Where VF and m are the forward voltage and
number of the white LEDs, Rout is the output
resistance of the SP6683.
The equation for the voltage divider R1 and R2
with VMODE = 1.25V is:
VTH = 1.25V • (1+R1/R2)
Which can be expressed as R1:
R1 = [(VTH/1.25) - 1] R2
For the typical SP6683 application, using VF =
3.6V, m = 8, ILED = 15mA, ROUT = 6Ω, VTH will
be 4.63V, Select R2 = 100kΩ, then R1 = 270kΩ

ESR capacitors.

Brightness Matching
For white LEDs, the forward voltage drop is a
function of the operating current. However, for
a given current, the forward voltage drop across
each LED does not always match exactly. This
can cause uneven brightness in the white LEDs.
used. This could be done by using a larger
resistor, as shown in the figure below. Rb2 is
used to bias the operating current of the white
LED, Rb1 is use to increase the output voltage.
Better brightness matching was achieved at the
cost of the power wasted on the bias resistor.
In the figure below, assuming high-precision
bias resistors were used, the operating current
ratio of two different branches can be easily
derived as shown by:
