Attention in Use

●

Output Capacitors

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 recommends the ESR of ceramic

capacitor be under 10 Ω.

●

Mounting

The long distance between IC and output capacitor might affect phase compensation by impedance in wire and inductor. For

stable power supply, output capacitor need to mount near IC as much as possible. Also VIN and GND pattern need to be

large and make the wire impedance small as possible.

●

Permissible Loss

Please have enough design patterns for expected maximum permissible loss. And under consideration of ambient

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

Overcurrent protection 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 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 recommends inserting failsafe system into the design.
