(note that if the s3 is forced high and s5 is forced low, then vttref is discharged and vtt is at high-z state. such condition is not recommended.) thermal shutdown a thermal shutdown circuit limits the junction tempera- ture of the apl5338a. when the junction temperature ex- ceeds +150 o c , the device will turn off the mosfets, al- lowing the device to cool down. the regulator regulates the output again through initiation of a new soft-start cycle after the junction temperature cools by 30 o c , resulting in a pulsed output during continuous thermal overload conditions. the thermal shutdown is designed with a 30 o c hysteresis to lower the average junction tempera- ture during continuous thermal overload conditions, ex- tending lifetime of the device. for normal operation, de- vice power dissipation should be externally limited so that junction temperatures will not exceed +125 o c .
