SNVS188G – MAY 2004 – REVISED DECEMBER 2005

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.
