Therefore the higher peak current in the system is not a problem. The other parameter that has to be checked is the power dissipation of the diode. It has ...
AEROSEMI - Olimex
www.olimex.comSchottky diode is a good choice for MT3608 because of its low forward voltage drop and fast reverses recovery. Using Schottky diode can get better efficiency. The highspeed rectification is also a good characteristic of Schottky diode for high switching frequency. Current rating of the diode must meet the root mean square of the peak current and
