tcr5sb18a tcr5sb50a 2014-03-01 7 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 recommend the esr of ceramic capacitor is under 10 ? . mounting the long distance between ic and output capacitor might af fect 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. permissible loss 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 maximu m dissipation rating is 70 to 80 percent. overcurrent protection circuit 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 hand book?. then use these products under absolute maximum ratings in any condition. furthermore, toshiba reco mmend inserting failsafe system into the design.
