R1218x SERIES
Step-up DC/DC converter for White LED Backlight
NO.EA-166-070905
OUTLINE
The R1218x Series are PWM control type step-up DC/DC converter ICs with low supply current.
The R1218x is fully dedicated to drive White LED with constant current. Each of these ICs consists of an
NMOS FET, an oscillator, a PWM comparator, a voltage reference unit, an error amplifier, an under voltage
lockout circuit (UVLO), an over-voltage protection circuit (OVP), and so on.
The R1218x can drive white LEDs with high efficiency with low supply current. A diode is built-in the
R1218xxx1A, therefore it is possible to drive up to 4LEDs without an external diode. The R1218xxx2A, an
external diode is necessary, however, up to 6 serial LEDs can be driven with the R1218xxx2A.
Constant current can be set with an external resistance value. Dimming control is possible by PWM signal for
CE pin. Feedback voltage is 0.2V, therefore power loss by current setting resistance is small and efficiency is
good. Maximum duty cycle is internally fixed, Typ. 91%. LEDs can be driven from low voltage. Protection circuits
are the current limit of Lx peak current, the over voltage limit of output, and the under voltage lockout function.
Packages are standard SOT-23-6 and very tiny PLP1820-6.

• LED Current setting
LED current can be set with feedback resister(R1)
ILED=0.2 / R1
• LED Dimming Control, Softstart
(1) LED dimming control by PWM signal to CE pin
LED dimming control is possible by forcing PWM signal to CE pin.
When the power-on or start up with CE pin, softstart function works, however, after that, if the CE pin is set
as "L" and set CE pin "H" again during the shutdown delay time, softstart function is disabled and starts up
fast to normal mode, therefore 200Hz to 5kHz PWM signal is standard. By the CE pin input, LED turns on
and off. Average LED current varies depending on the duty cycle of CE input. Too high frequency PWM
signal is not effective because of its delay.

(2) Dimming control by DC voltage
LED dimming control is also possible by using the DC voltage to VFB pin. LED current is adjustable by DC
voltage and resisters, R1 and R2 in the following figure.
ILED=(DC − 0.2) / R2 − 0.2 / R1

(3) Dimming control by feedback voltage and filtered PWM signal
LED dimming control is also possible by using the feedback voltage and filtered PWM signal.
LED current is adjustable according to the "H" level (VH) and "L" level(VL) of PWM signal and resisters,

Dimming controle by filtered PWM signal
R1, R2, R3, and R4 in the figure5. Duty=0% to 100% PWM signal duty cycle can be used up to the
maximum LED current and minimum LED current as in the next formulas.
ILEDMIN=(0.2 − R2 × (VH − 0.2) / (R3 + R4)) / R1
ILEDMAX=(0.2 − R2 × (VL − 0.2) / (R3 + R4)) / R1
For example, supposed that the PWM signal level is set as 2.5V/0V, to adjust the LED current range from 0mA
to 20mA by the duty cycle, our recommendation external components values are, R1=10Ω, R2=5.1kΩ,
R3=51kΩ, R4=5.1kΩ or around.
C3 should be set large enough to regard the PWM signal as adjustable DC voltage by the filter. In this method,
higher frequency control than the frequency against the CE pin can be used for dimming control.
For example, if the frequency is 40kHz, 0.1µF or more capacitor is our recommendation value as C3.

• Selection of Inductors
The peak current of the inductor at normal mode can be calculated as next formula:
ILXpeak=1.25 × ILED × VOUT / VIN + 0.5 × VIN × (VOUT − VIN) / (L × VOUT × fosc)
When the start-up or dimming control by CE pin, transient current flows, the peak current must be equal or
less than the current limit of the IC. The peak current should not beyond the rating current of the inductor. For
example, for 4 serial LED drive from VIN=3.6V, recommendation value of the inductor is 22µH or more.
• Selection of Capacitors
Set 1µF or more value bypass capacitor C1 between VIN pin and GND pin as close as posible.
Set 0.22µF or more capacitor C2 between VOUT and GND pin.
