Precautions
Mount the external capacitors, the diode and the coil as close as possible to the IC, and secure grounding
at a single location.
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 coil, the
capacitor and impedance of power supply used, fully check them using an actually mounted model.
The overload protection circuit of this IC performs the protective function by detecting the maximum duty
time (100 %). In choosing the components, make sure that over currents generated by short-circuits in
the load, etc., will not surpass the allowable dissipation of the switching transistor and inductor.
Make sure that dissipation of the switching transistor (especially at a high temperature) does not exceed
the allowable dissipation of the package.
Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in
electrostatic protection circuit.
SII claims no responsibility for any and all disputes arising out of or in connection with any infringement of
the products including this IC upon patents owned by a third party.
