(8) output over load protection function fb olp comparator the output overload protection monitors the se condary output load status at the fb pin. this function stops a switching when an overload occurs. when there is an overload, the out put voltage is dropped and the photo coupler current becomes zero, so the fb pin voltage is rised. when the fb pin voltage > v folp1a (2.8 v typ) continuously for the period t folp2 (32 ms typ), it is judged as an overload and stops switching. when the fb pin > fv folp1a (2.8 v typ), if the voltage goes lower than v folp1b (2.6v typ) during the period t folp2 (32 ms typ), the overload protection timer is reset. the swit ching operation is performed during this period t folp2 (32ms typ) at startup, the fb voltage is pulled up to the ic?s internal voltage, so the operation starts at a voltage of v folp1a (2.8 v typ) or above. therefore, at startup t he fb voltage must be set to go to v folp1b (2.6 vtyp) or below during the period t folp1 (32 ms typ), and the secondary output voltage?s start time must be set within the period t folp2 (32 ms typ) following startup of the ic. recovery from the once detection of fbolp, after the period t folp2 (512 ms typ) figure 15. over load protection (auto recovery) a: the fbolp comparator detects over load for fb>v folp1a b: states of a continuously for the period t folp2 (32 ms typ), it is judged as an overload and stops switching. c: while switching stops for the over load protection function, the vcc pin vo ltage drops and vcc pin voltage reaches < v chg , the vcc charge function operates so the vcc pin voltage rises. d: vcc charge function stops when vcc pin voltage > v chg2 e: if t olpst typ =512ms go on from b point, switching function starts on soft start. f: if t folp2 typ=32ms go on from e point to continues a overload condition (fb>v folp1a ), switching function stops at f point. g: while switching stops vcc pin voltage drops to < v chg1 , vcc charge function operates and vcc pin voltage rises. h: if vcc pin (1pin) voltage becomes over v chg2 by the vcc charge function, vcc charge function operation stops

(2) power supply and ground lines in the board pattern design, power supply and ground lines should be routed so as to achieve low impedance. if there are multiple power supply and ground lines, be careful wi th regard to interference caused by common impedance in the routing pattern. with regard to ground lines in particular, be careful regarding the separation of large current routes and small signal routes, including the external circuits. also , with regard to all of the lsi?s power supply pins, in addition to inserting capacitors between the power supply and ground pins, when using capacitors there can be problems such as capacitance losses at low temperature, so check thoroughly as to whet her there are any problems with the characteristics of the capacitor to be used before determining constants. (3) ground potential the ground pin?s potential should be set to the mini mum potential in relation to the operation mode. (4) pin shorting and attachment errors when attaching ics to the set board, be careful to avoid errors in the ic?s orientation or position. if such attachment errors occur, the ic may become damaged. also, damage may occur if foreign matter gets between pins, between a pin and a power supply line, or between ground lines. (5) operation in strong magnetic fields note with caution that these products may become damaged when used in a strong magnetic field. (6) input pins in ic structures, parasitic elements are inevitably formed according to the relation to potential. when parasitic elements are active, they can interfere with circuit operatio ns, can cause operation faults, and can even result in damage. accordingly, be careful to avoid use methods that enable para sitic elements to become active, such as when a voltage that is lower than the ground voltage is app lied to an input pin. also, do not apply voltage to an input pin when there is no power supply voltage being applied to the ic. in fact, even if a power supply voltage is being applied, the voltage applied to each input pin should be either below the power supply vo ltage or within the guaranteed values in the electrical characteristics. (7) external capacitors when a ceramic capacitor is used as an external capacitor, consider possible reduction to below the nominal capacitance due to current bias and capacitance fluct uation due to temperature and the like before determining constants. (8) thermal design the thermal design should fully consider allowable dissipation (pd) under actual use conditions. also, use these products within ranges that do not put output tr beyond the rated voltage and aso. (9) rush current in a cmos ic, momentary rush current may flow if the intern al logic is undefined when the power supply is turned on, so caution is needed with regard to the power supply coup ling capacitance, the width of power supply and gnd pattern wires, and how they are laid out. (10) handling of test pins and unused pins test pins and unused pins should be handled so as not to caus e problems in actual use conditions, according to the descriptions in the function manual, app lication notes, etc. contact us regard ing pins that are not described. (11) document contents documents such as application notes are design documents used when designing applications, and as such their contents are not guaranteed. before finalizing an applicati on, perform a thorough study and evaluation, including for external parts. status of this document the japanese version of this document is fo rmal specification. a customer may use this translation version only for a reference to help reading the formal version. if there are any differences in translation version of this document formal version takes priority.
