• 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 recommend the ESR of ceramic capacitor is under 10 Ω.
• Mounting 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 pos sible. 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 surrounding temperature, input voltage, a nd output current etc, we recommend proper dissipation ratings for maximum permissible loss; in general maximum dissipation rating is 70 to 80 percent.
• Over current Protection and Thermal shut down function Over current protection and Thermal shut down function are designed in these products, but these are not designed to constantly ensure the suppression of the device within operation limits . Depending on the condition during actual usage, it could affect the electrical characteristic specification and re liability. Also note that if output pins and GND pins are not completely shorted out, these products might be break down. When using these products, please read through and understand the concept of dissipation for absolute maximum ratings from the above m ention 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.
