Attention in Use
● Output Capacitors
● Mounting
● Permissible Loss
● Overcurrent Protection Circuit
Ceramic capacitors can be used for these devices. However, because of the type of the capacitors, there might be
unexpected thermal features. Please consider application condition for selecting capacitors. And Toshiba
recommend the ESR of ceramic capacitor is under 10 Ω.
The long distance between IC and output capacitor might affect phase assurance by impedance in wire and inductor.
For stable power supply, output capacitor need to mount near IC as much as possible. Also GND pattern need to be
large and make the wire impedance small as possible.
Please have enough design patterns for expected maximum permissible loss. And under consideration of
surrounding temperature, input voltage, and output current etc, we recommend proper dissipation ratings for
maximum permissible loss; in general maximum dissipation rating is 70 to 80 percent.
Overcurrent protection circuit is designed in these products, but this does not assure for the suppression of uprising
device operation. If output pins and GND pins are shorted out, these products might be break down.
In use of these products, please read through and understand dissipation idea for absolute maximum ratings from
the above mention or our ‘Semiconductor Reliability Handbook’. Then use these products under absolute maximum
ratings in any condition. Furthermore, Toshiba recommend inserting failsafe system into the design.
