3 / 19 page STCF02 Application 3/19 1 Application Table 1. External components Note: - 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 CCOMP is optional and may be used if the error amplifier bandwidth (which by default is 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. Figure 1. Application circuit Symbol Parameter Min. Typ. Max.
