Application
- The external components proposal should be considered as a design reference guide. The
performances mentioned in the electrical characteristics table are not guaranteed for all the
possible electrical parameters of the components included in this list. On the other hand the
operation of STCF02 is not limited with the use of the external components listed above.
- The C
set to 2 KHz) has to be decreased because of an unstable driver function. Unstable operation
could be caused by using different values of inductor and output capacitor then recommended.
