XC9131 Series
■ TYPICAL APPLICATION CIRCUIT
● XC9131 Series
<XC9131 Series Output Voltage Setting>
Output voltage can be set by adding external split resistors.
Output voltage is determined by the following equation,
based on the values of R FB1 and R FB2 . The sum of R FB1 and R FB2 should normally be 1000k Ω or less.
V OUT =0.5×(R FB1 +R FB2 )/R FB2
The value of C FB , speed-up capacitor for phase compensation, should be 0pF or fzfb = 1/(2 π× C FB × R FB1 ) which is higher
than 20 kHz. Also, when the input voltage, V IN is lower than 1.5V, C FB is 0pF. Adjustments are depending on
application, inductance (L), load capacitance (C L ) and dropout voltage.
[Example of calculation]
When R FB1 =560k ? ,R FB2 =100k ? , V OUT =0.5×(560k+100k)/100k=3.3V
When C FB =10pF, fzfb=1/ （ 2 π ×10p×560k ） =28.42kHz

C DD :
2.2 μ H ～ 4.7 μ H
VLCF4020 series, LTF5022-LC series
Should be selected in 20 μ F or higher
Capacitor JMK212BJ106KG × 2 、 LMK212BJ106KG × 2 、 LMK316BJ226ML is recommended.
Ceramic capacitor: B (JIS standard) or X7R, X5R (EIA standard)
10 μ F
Capacitor JMK212BJ106KG or LMK212BJ106KG is recommended.
Ceramic capacitor: B (JIS standard) or X7R, X5R (EIA standard)
0.47 μ F (Ceramic capacitor)
* V DD voltage is constantly applied to the C DD capacitor. While selecting a part, please concern about capacitance reduction and voltage
durability.
* For the coil L, please use 2.2 μ H to 4.7 μ H.
However, when the input voltage V IN is lower than 1.5V, please use 2.2 μ H.
* Capacitance C L is recommended 20 μ F or higher. (Ceramic capacitor compatible)
When you select the external components, please consider capacitance loss and voltage durability.
* If using tantalum or low ESR electrolytic capacitors please be aware that ripple voltage will be higher due to the larger ESR (Equivalent
Series Resistance) values of those types of capacitors. Please also note that the IC’s operation may become unstable with such
capacitors so that we recommend to test on the board before usage.
* If using electrolytic capacitor for the C L , please connect a ceramic capacitor in parallel.
