DN-51 Programming the UCC3806 Features

The UCC3806 is a pin-for-pin-compatible BiCMOS replacement for the UC3846 and UC3856. However this design note explains how some functions in the UCC3806 are programmed differently. In particular the CUR LIM ADJ pin programs the maximum peak current for the current-sense amplifier. This function is completely compatible with that of previous ICs. The second function on this pin is the latch/non-
