R1200x SERIES
STEP-UP DC/DC CONVERTER FOR OLED BACK LIGHT with SHUTDOWN FUNCTION
NO.EA-192-170925
OUTLINE
R1200x series are CMOS-based control type step-up DC/DC converter with low supply current ICs. Each of
these ICs consists of a Nch MOSFET, NPN transistor, an oscillator, PWM comparator, a voltage reference unit,
an error amplifier, a current limit circuit, an under voltage lockout circuit (UVLO), an over voltage protection circuit
(OVP), and a soft start circuit. As the external components, an inductor, resistances or capacitors are necessary
to make a constant output voltage of step-up DC/DC converter with the R1200x. At standby mode, the NPN
transistor can separate the output from the input. During the situation of that, there are two versions. R1200xxxxA:
the output of VOUT is generated to 0V by the low resistance (with the auto discharge function). R1200xxxxB does
not generate the output of VOUT (without the auto discharge function).
The soft-start time (Typ. 1.5ms) and the maximum duty cycle (Typ. 91%) are set internally. For the protection
functions of R1200x series are the current limit function of the LX peak current, the OVP function for detection the
over voltage of output and the UVLO function for protective miss-operation by the low voltage. (The threshold of
OVP is selectable from 17V, 19V or 21V.)
Since the packages for these ICs are DFN1616-6, DFN(PLP)1820-6, SOT-23-6 and WLCSP-6-P1, therefore
high density mounting of the ICs on boards is possible.

There are two operation modes of the step-up PWM control-DC/DC converter. That is the continuous mode and
discontinuous mode by the continuousness inductor.
When the transistor turns ON, the voltage of inductor L becomes equal to VIN voltage. The increase value of
inductor current (i1) will be

As the step-up circuit, during the OFF time (when the transistor turns OFF) the voltage is continually supply from
the power supply. The decrease value of inductor current (i2) will be
∆i2 = (VOUT − VIN) × topen / L .......................................................................................... Formula 2
At the PWM control-method, the inductor current become continuously when topen=toff, the DC/DC converter
operate as the continuous mode.
In the continuous mode, the variation of current of i1 and i2 is same at regular condition.
VIN × ton / L = (VOUT - VIN) × toff / L .................................................................................. Formula 3
The duty at continuous mode will be
duty (%)= ton / (ton + toff) = (VOUT - VIN) / VOUT ................................................................ Formula 4
The average of inductor current at tf = toff will be
IL(Ave.) = VIN × ton / (2 × L) ........................................................................................... Formula 5
If the input voltage = output voltage, the IOUT will be
IOUT = VIN2 × ton / (2 × L × VOUT) ...................................................................................... Formula 6
If the IOUT value is large than above the calculated value (Formula 6), it will become the continuous mode, at this
status, the peak current (ILmax) of inductor will be
ILmax = IOUT × VOUT / VIN + VIN × ton / (2 × L) ................................................................... Formula 7
ILmax = IOUT × VOUT / VIN + VIN × T × (VOUT - VIN) / (2 × L × VOUT) ..................................... Formula 8
The peak current value is larger than the IOUT value. In case of this, selecting the condition of the input and the
output and the external components by considering of ILmax value.
The explanation above is based on the ideal calculation, and the loss caused by LX switch and the external
components are not included.
The actual maximum output current will be between 50% and 80% by the above calculations. Especially, when
the IL is large or VIN is low, the loss of VIN is generated with on resistance of the switch. Moreover, it is necessary
to consider Vf of the diode (approximately 0.8V) about VOUT.

Shutdown
⋅ At standby mode, the output is completely separated from the input and shutdown by the NPN transistor of

⋅
internal IC. However, the leakage current is generated when the LX pin voltage is equal or more than VIN pin
voltage at standby mode.
R1200xxxxA (with auto discharge function): In the term of standby mode, the switch is turned ON between VOUT
to GND and the VOUT capacitor is discharged.
R1200xxxxB (without auto discharge function): The built-in switch for discharge does not turn on, but the OVP
sense resistors between VOUT and GND exists as same as A version.
However, the both version (A/B) has the OVP sense resistance (4 to 5MΩ) between VOUT and GND (refer to
OVP sense current (IVOUT) on ELECTRICAL CHARACTERISTICS table) and the current flows through from VOUT
to GND.

Selection of Inductors
The peak current of the inductor at normal mode can be estimated as the next formula when the efficiency is
80%.
ILmax=1.25 x IOUT x VOUT / VIN + 0.5 x VIN x (VOUT - VIN) / (L x VOUT x fosc)
In the case of start-up or dimming control by CE pin, inductor transient current flows, and the peak current of it
must be equal or less than the current limit of the IC. The peak current should not beyond the rated current of
the inductor.
The recommended inductance value is 4.7 µH – 22 µH.

External Components Setting
⋅ If the spike noise of VOUT may be large, the spike noise may be picked into VFB pin and make the operation
unstable. In this case, use a R3 of the resistance value in the range from 1kΩ to 5kΩ to reduce a noise level of
VFB.
The Method of Output Voltage Setting
⋅ The output voltage can be calculated with divider resistors (R1 and R2) values as the following formula:
Output Voltage = VFB × (R1 + R2) / R1
⋅ The total value of R1 and R2 should be equal or less than 300kΩ. Make the VIN and GND line sufficient. The
large current flows through the VIN and GND line due to the switching. If this impedance (VIN and GND line) is
high, the internal voltage of the IC may shift by the switching current, and the operating may become unstable.
Moreover, when the built-in LX switch is turn OFF, the spike noise caused by the inductor may be generated.
As a result of this, recommendation voltage rating of capacitor (C2) value is equal 1.5 times larger or more than
the setting output voltage.

TECHNICAL NOTES
Current Path on PCB
The current paths in an application circuit are shown in Fig. 1 and 2.
A current flows through the paths shown in Fig. 1 at the time of MOSFET-ON, and shown in Fig. 2 at the time
of MOSFET-OFF. In the paths pointed with red arrows in Fig. 2, current flows just in MOSFET-ON period or
just in MOSFET-OFF period. Parasitic impedance/inductance and the capacitance of these paths influence
stability of the system and cause noise outbreak. So please minimize this side effect. In addition, please shorten
the wiring of other current paths shown in Fig. 1 and 2 except for the paths of LED load.
Layout Guide for PCB
⋅
Please shorten the wiring of the input capacitor (C1) between VIN pin and GND pin of IC. The GND pin should
be connected to the strong GND plane.
⋅
The area of LX land pattern should be smaller.
⋅
Please put output capacitor (C2) close to the VOUT pin.
⋅
Please make the GND side of output capacitor (C2) close to the GND pin of IC.
