8. Ground wiring pattern
9 . Selection of inductor
If small-signal GND and large-current GND are provided, It will be recommended to separate the large-current GND pattern from
the small-signal GND pattern and establish a single ground at the reference point of the set PCB so that resistance to the wiring
pattern and voltage fluctuations due to a large current will cause no fluctuations in voltages of the small-signal GND. Pay attention
not to cause fluctuations in the GND wiring pattern of external parts as well.
It is recommended to use an inductor with a series resistance element (DCR) 0.1Ω or less. Note that use of a high DCR
inductor will cause an inductor loss, resulting in decreased output voltage. Should this condition continue for a specified
period (soft start time + timer latch time), output short circuit protection will be activated and output will be latched OFF.
When using an inductor over 0.1Ω, be careful to ensure adequate margins for variation between external devices and this
IC, including transient as well as static characteristics. Furthermore, in any case, it is recommended to start up the output
with EN after supply voltage is within operation range.
