Notes:
Note5: The ON/OFF control function can be positive or negative logic. The pin voltage is referenced to -Vin pin
Note6: Measurements are made for 5Vout with a 1µF/25V X7R MLCC and a 22µF/25V E-Cap; for 15Vout
with a 22µF/25V X7R MLCC, for 24Vout with a 4.7µF/50V X7R MLCC and for 48Vout with a 2.2µF/100V X7R MLCC
Note7: Refer to page PB-5 Remote Sense. If not used connect Remote Sense pins to corresponding output pins
