EL7513
White LED Step-Up Regulator
DATASHEET
The EL7513 is a constant current boost regulator specially
designed for driving white LEDs. It can drive 4 LEDs in
series or up to 12 LEDs in parallel/series configuration and
achieves efficiency up to 91%.
Features
The brightness of the LEDs is adjusted through a voltage
level on the CNTL pin. When the level falls below 0.1V, the
chip goes into shut-down mode and consumes less than
1µA of supply current for VIN less than 5.5V.
• Drives up to 12 LEDs
The EL7513 is available in the 8 Ld TSOT and 8 Ld MSOP
packages. The TSOT package is just 1mm high, compared
to 1.45mm for the standard SOT23 package.
• 1µA maximum shut-down current

FIGURE 18. DISCONTINUOUS CONDUCTION MODE
Detailed Description
The EL7513 is a constant current boost regulator specially
designed for driving white LEDs. It can drive up to 4 LEDs in
series or 12 LEDs in parallel/series configuration and
achieves efficiency up to 91%.
The brightness of the LEDs is adjusted through a voltage
level on the CNTL pin. When the level falls below 0.1V, the
chip goes into shut-down mode and consumes less than
1µA of current for VIN less than 5.5V.
Steady-State Operation
EL7513 is operated in constant frequency PWM. The
switching is around 1MHz. Depending on the input voltage,
the inductance, the type of LEDs driven, and the LED’s
current, the converter operates at either continuous
conduction mode or discontinuous conduction mode (see
waveforms). Both are normal.
Brightness Control
LED’s current is controlled by the voltage level on CNTL pin
(VCNTL). This voltage can be either a DC or a PWM signal
with frequency less than 200Hz (for C3 = 4700pF). When a
higher frequency PWM is used, an RC filter is recommended
before the CNTL pin (see Figure 20).
FIGURE 19. OVER VOLTAGE PROTECTION (LED
DISCONNECTED)
The relationship between the LED current and CNTL voltage
level is as follows:
V CNTL
I LED = ---------------------------13.33 R 1
(EQ. 1)
When R1 is 5, 1V of VCNTL conveniently sets ILED to
15mA. The range of VCNTL is 250mV to 5.5V.
Shut-Down
When VCNTL is less than 100mV, the converter is in shutdown mode. The max current consumed by the chip is less
than 1µA for VIN less than 5.5V.
Over-Voltage Protection
When an LED string is disconnected from the output, VO will
continue to rise because of no current feedback. When VO
reaches 18V (nominal), the chip will shut down. The output
voltage will drop. When VO drops below 16V (nominal), the
chip will boost output voltage again until it reaches 18V. This
hiccough continues until LED is applied or converter is shut
down.
When designing the converter, caution should be taken to
ensure the highest operating LED voltage does not exceed
17V, the minimum shut-down voltage. There is no external
component required for this function.

COMP
The input and output capacitors are not very important for
the converter to operate normally. The input capacitance
is normally 0.22µF - 4.7µF and output capacitance
0.22µF - 1µF. Higher capacitance is allowed to reduce the
voltage/current ripple, but at added cost. Use X5R or X7R
type (for its good temperature characteristics) of ceramic
capacitors with correct voltage rating and maximum height.

When choosing an inductor, make sure the inductor can
handle the average and peak currents giving by following
formulas (80% efficiency assumed):
The diode should be Schottky type with minimum reverse
voltage of 20V. The diode's peak current is the same as
inductor's peak current, the average current is IO, and RMS
current is:
IO VO
I LAVG = -----------------------0.8 V IN
(EQ. 2)
I DRMS =
1
I LPK = I LAVG + --- I L
2
(EQ. 3)
Ensure the diode's ratings exceed these current
requirements.
V IN V O – V IN
I L = --------------------------------------------L VO FS
(EQ. 4)
• IL is the peak-to-peak inductor current ripple in Ampere
• L inductance in µH
• FS switching frequency, typical 1MHz
A wide range of inductance (6.8µH - 68µH) can be used for
the converter to function correctly. For the same series of
inductors, the lower inductance has lower DC resistance
(DCR), which has less conducting loss. But the ripple current
is bigger, which generates more RMS current loss. Figure 11
shows the efficiency of the demo board under different
inductance for a specific series of inductor. For optimal
efficiency in an application, it is a good exercise to check
several adjacent inductance values of your preferred series
of inductors.
For the same inductance, higher overall efficiency can be
obtained by using lower DCR inductor.

L = 22µH
L = 33µH
L = 15µH
However, placing LEDs into series/parallel connection can
give higher efficiency as shown in the efficiency curves. One
of the ways to ensure the brightness uniformity is to prescreen the LEDs.
PCB Layout Considerations
The layout is very important for the converter to function
properly. Power Ground ( ) and Signal Ground ( ) should
be separated to ensure the high pulse current in the power
ground does not interference with the sensitive signals
connected to Signal Ground. Both grounds should only be
connected at one point right at the chip. The heavy current
paths (VIN-L-LX pin-PGND, and VIN-L-D-C2-PGND) should
be as short as possible.
The trace connected to the CS pin is most important. The
current sense resister R1 should be very close to the pin
When the trace is long, use a small filter capacitor close to
the CS pin.
The demo board is a good example of layout based on the
principle. Please refer to the EL7513 Application Brief for the
layout.

One leg of LEDs connected in series will ensure the
uniformity of the brightness. 18V maximum voltage enables
4 LEDs can be placed in series.
The heat of the IC is mainly dissipated through the PGND
pin. Maximizing the copper area around the plane is
preferable. In addition, a solid ground plane is always helpful
for the EMI performance.
