Abstract: synchronize to an external clock that may be problematic with an AS384x. When it is desired to synchronize , both UC384x parts and for the AS384x. These schemes share a general requirement that the sync , might be seen in a given power supply when a UC384x is replaced by an AS384x, or vice versa. Whether or , behavior of the control chip. AS384x/UC384x Compatibility Issues Application Note 4 cycle programming , Synchronization is generally not used in the power supplies typical of 384x designs, but the Astec AS384x parts -
