● Setting of Output Voltage
Output voltage (1.8V to 5.0V recommended range of voltage) can be set with divider resistors for voltage setting,
R1 and R2 as shown in the typical application. Refer to the next formula.
Output Voltage = VFB × (R1 + R2) / R1
(VFB = 0.6V)
Recommended value of resistors (R1 + R2) is lower than 100k.
Make sufficient power supply and ground and reinforce supplying. The large switching current could flow
through the connection of power supply, inductor, ground, diode and the connection of VOUT. If the impedance of
the connection of power supply and ground is high, the voltage level of power supply of the IC fluctuates with the
switching current. We recommend you to use output capacitor and diode with an allowable voltage at least 1.5
times as much as setting output voltage. This is because there may be case where a spike-shaped high voltage is
generated by an inductor when built-in transistor is on and off.
Use a diode of a Schottky type with high switching speed, low reverse current and also pay attention to its
current capacity.
Set external components as close as possible to the IC and minimize the connection between the components
and the IC. In particular, output capacitor should be connected to VOUT pin with IC ground by the minimum
connection, because this IC uses the VOUT voltage as the main power supply, after start-up. Use capacitors with a
capacity of 10
μF or more for VOUT pin. We recommend you to set a ceramic capacitor (10μF) between VIN and
ground.
The divider resistors should be placed as close as possible to the IC ground pin. VFB line is recommended to
use short line as well to avoid the influence of noise.
Please select the inductor value 10
μH in the case of VOUT≧2.5V and 6.8μH in the case of VOUT<2.5V. Choose
an inductor that has sufficiently small D.C. resistance and large allowable current and is hard to reach magnetic
saturation. And if the value of inductance of an inductor is extremely small, the ILX may exceed the absolute
maximum rating at the maximum loading. Use an inductor with appropriate inductance. (Refer to next Output
Current of Step-up Circuit and External Components)
*
The performance of power circuit using those ICs extremely depends upon the peripheral circuits. Pay
attention in the selection of the peripheral circuits. In particular, design the peripheral circuits in a way that the
values such as voltage, current, and power of each component, PCB patterns and the IC do not exceed their
respected rated values. (such as the voltage, current , and power)
