Fuse: External fast blow fuse with a rating of 30A. The recommended fuse model is 314030P from LITTLEFUSE. Remote ON/OFF The converter is equipped with a primary ON/OFF (CNT) pin used to remotely turn the converter on or off via a system signal. Two CNT logic options are available. For the positive logic model a system logic low signal will turn the converter off. For the negative logic model a system logic high signal will turn the converter off. For negative logic models where no control signal will be used the ON/OFF pin should be connected directly to -Vin to ensure proper operation. For positive logic models where no control signal will be used the ON/OFF pin should be left unconnected.

While connecting it between Trim and Vo+ will increase the output voltage. The following equations determine the external resistance to obtain the trimmed output voltage. 100% R trim − down = ( − 2) kΩ ∆% V (100% + ∆%) 100% − − 2) kΩ R trim − up = ( nominal 1.225∆% ∆% ∆% = Vnominal − Vdesired × 100 % Vnominal V norm : Nominal output voltage.
