Precautions
• Mount the external capacitors, the diode, and the coil as close as possible to the IC.
• Characteristics ripple voltage and spike noise occur in IC containing switching regulators. Moreover, rush current flows
• Make sure that the dissipation of the switching transistor (especially at a high temperature) does not exceed the
• The performance of this IC varies depending on the design of the PCB patterns, peripheral circuits and external parts.
• When the impedance of the power supply is high, the shutdown pin is switched from “L” to “H”, or V
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
• SII claims no responsibility for any and all disputes arising out of or in connection with any infringement of the products
