OUTPUT DIODE SELECTION
A Schottky diode should be used for the output diode. The forward current rating of the diode should be higher
than the peak input current, and the reverse voltage rating must be higher than the output voltage. Do not use
ordinary rectifier diodes, since slow switching speeds and long recovery times cause the efficiency and the load
regulation to suffer. Table 1 shows a list of the diode manufacturers.
WSON PACKAGE DEVICES
The LM2623 is offered in the 14 lead WSON surface mount package to allow for increased power dissipation
compared to the VSSOP-8. For details of the thermal performance as well as mounting and soldering
specifications, refer to (SNOA401) Application Note AN-1187.
