DESCRIPTION
The SP6691 is a micro power boost regulator that is specifically designed for powering series
configuration white LED. The part utilizes fixed off time architecture and consumes only 10nA
quiescent current in shutdown. Low voltage operation, down to 1V, fully utilizes maximal battery
life. The SP6691 is offered in a 8 Pin DFN, 5-pin SOT-23 or 5 Pin TSOT package and enables
the construction of a complete regulator occupying < 0.2 in2 board space.

THEORY OF OPERATION
General Overview:
At the end of the 250ns time period, driver
transistor is again allowed to turn on which
ramps the current back up to the 450mA level.
Comparator X2 clears the latch, it’s output turns
off the driver transistor, and this allows delivery
of L1’s stored kinetic energy to C2. This switching action continues until the output capacitor
voltage is charged to the point where FB is at
band gap (1.22V). When this condition is
reached, X1 turns off the internal circuitry and
the cycle repeats.
Operation can be best understood by referring to
the functional diagram above and the typical
application circuit in the front page. Q1 and Q2
along with R3 and R4 form a band gap reference. The input to this circuit completes a feedback path from the high voltage output through
a voltage divider, and is used as the regulation
control input. When the voltage at the FB pin is
slightly above 1.22V, comparator X1 disables
most of the internal circuitry. Current is then
provided by capacitor C2, which slowly discharges until the voltage at the FB pin drops
below the lower hysteresis point of X1, about
6mV. X1 then enables the internal circuitry,
turns on chip power, and the current in the
inductor begins to ramp up. When the current
through the driver transistor reaches about
450mA, comparator X2 clears the latch, which
turns off the driver transistor for a preset 250nS.
At the instant of shutoff, inductor current is
diverted to the output through diode D1. During
this 250nS time limit, inductor current decreases
while its energy charges C2.

APPLICATION INFORMAMTION
Inductor Selection
Capacitor Selection
For SP6691, the internal switch will be turned
off only after the inductor current reaches the
typical dc current limit (ILIM=450mA). However, there is typically propagation delay of
200nS between the time when the current limit
is reached and when the switch is actually turned
off. During this 200nS delay, the peak inductor
current will increase, exceeding the current limit
by a small amount. The peak inductor current
can be estimated 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.
IPK = ILIM +
VIN(MAX)
For the typical application, 4.7µF input capacitor and 2.2µF output capacitor are sufficient.
The input and output ripple could be further
reduced by increasing the value of the input and
output capacitors. Place all the capacitors as
close to the SP6691 as possible for layout. For
use as a voltage source, to reduce the output
ripple, a small feedforward (47pF) across the
top feedback resistor can be used to provide
sufficient overdrive for the error comparator,
thus reduce the output ripple.
• 200nS
L
The larger the input voltage and the lower the
inductor value, the greater the peak current.
In selecting an inductor, the saturation current
specified for the inductor needs to be greater
than the SP6691 peak current to avoid saturating
the inductor, which would result in a loss in
efficiency and could damage the inductor.
Refer to Table 2 for some suggested low ESR
capacitors.
Table 2. Suggested Low ESR Capacitor
Choosing an inductor with low DCR decreases
power losses and increase efficiency.
Refer to Table 1 for some suggested low ESR
inductors.

LED Current Program
In the white LEDs application, the SP6691 is
generally programmed as a current source. The
bias resistor Rb, as shown in the typical application circuit is used to set the operating current of
the white LED using the equation:
Diode Selection
A schottky diode with a low forward drop and
fast switching speed is ideally used here to
achieve high efficiency. In selecting a Schottky
diode, the current rating of the schottky diode
should be larger than the peak inductor current.
Moreover, the reverse breakdown voltage of the
schottky diode should be larger than the output
voltage.

precision resistors are recommended. Table 3
below shows the Rb selection for different white
LED currents. For example, to set the operating
current to be 20mA, Rb is selected as 60.4 Ω, as
shown in the schematic.

Dimming control can be achieved by applying a
PWM control signal to the SHDN pin. The
brightness of the white LEDs is controlled by
increasing and decreasing the duty cycle of the
PWM signal. A 0% duty cycle corresponds to
zero LED current and a 100% duty cycle corresponds to full load current. While the operating
frequency range of the PWM control is from
60Hz to 700Hz, the recommended maximum
brightness frequency range of the PWM signal
is from 60Hz to 200Hz. A repetition rate of at
least 60Hz is required to prevent flicker. The
magnitude of the PWM signal should be higher
than the minimum SHDN voltage high.
Output Voltage Program
The SP6691 can be programmed as either a
voltage source or a current source. To program
the SP6691 as voltage source, the SP6691 requires 2 feedback resistors R1 & R2 to control
the output voltage. As shown in Figure 22.

When any white LED inside the white LED
module fails or the LED module is disconnected
from the circuit, the output and the feedback
control will be open, thus resulting in a high
output voltage, which may cause the SW pin
voltage to exceed it maximum rating. In this
case, a zener diode can be used at the output to
limit the voltage on the SW pin and protect the
part. The zener voltage should be larger than the
maximum forward voltage of the White LED
module.

To further improve the efficiency and reduce the
effects of the ambient temperature on the diode
D1 used in method 1, an op amp circuit can be
used as shown in Figure 24. The gain of the op
amp circuit can be calculated by:
Power Efficiency
For the typical application circuit, the output
efficiency of the circuit is expressed by
Av =
R1 + R 2
R1
VOUT • IOUT
VIN • IIN
If the voltage across the bias resistor is set to be
0.1V the current through R1 and R2 to be around
100µA, R1 and R2 can be selected as 1K and
11.2K respectively. LMV341 can be used because of its small supply current, offset voltage
and minimum supply voltage. By using this
method, the efficiency can be increased around
7%.
Where VIN , IIN, VOUT, IOUT are the input and
output voltage and current respectively.
While the white LED efficiency is expressed by
η=
Murata LQH32CN100K11

This can reduce the copper trace resistance
which directly effects the input and output
ripples. The feedback resistor network should
be kept close to the FB pin to minimize copper
trace connections that can inject noise into the
system. The ground connection for the feedback
resistor network should connect directly to the
GND pin or to an analog ground plane that is tied
directly to the GND pin. The inductor and the
schottky diode should be placed as close as
possible to the switch pin to minimize the noise
coupling to the other circuits, especially the
feedback network.

This equation indicates that the white LED

efficiency of the circuit when VOUT is not very
large, compared to the feedback voltage (1.22V).

The other power is consumed by the bias resistor. To reduce this power loss, two circuits can
be used, as shown in Figure 23 and Figure 24. In
Figure 23, a general-purpose diode (for example, 1N4148) is used to bring the voltage
across the bias resistor to be around 0.7V. R1 is
used to create a loop that provides around 100µA
operating current for the diode. 3% efficiency
improvement can be achieved by using this
method.
