Precaution
Mount external capacitors, diodes, and inductor as close as possible to the IC.
Characteristics ripple voltage and spike noise occur in IC containing switching regulators. Moreover rush current
flows at the time of a power supply injection. Because these largely depend on the inductor, the capacitor and
impedance of power supply used, fully check them using an actually mounted model.
Make sure the dissipation of the switching transistor (especially at a high temperature) does not exceed the
allowable power dissipation of the package.
The performance of a switching regulator varies depending on the design of the PCB patterns, peripheral circuits,
and external parts. Thoroughly test all settings with your device.
The capacitor, diode, inductor and others used as external parts do not assure the operation at high temperature.
Evaluate fully using the actual application when designing.
This IC builds in soft start function, starts reference voltage gradually, and it is controlled so that FB pin voltage and
reference voltage become this potential. Therefore, keep in mind that it will be in a maximum duty state according
to the factor of IC exterior if FB pin voltage is held less than reference voltage.
Although the IC contains a static electricity protection circuit, static electricity or voltage that exceeds the limit of the
protection circuit should not be applied.
Seiko Instruments Inc. assumes no responsibility for the way in which this IC is used on products created using this
IC or for the specifications of that product, nor does Seiko Instruments Inc. assume any responsibility for any
infringement of patents or copyrights by products that include this IC either in Japan or in other countries.
