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.
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.
