DESCRIPTION
The EV3356DG-00A is an evaluation board for
the MP3356, a fast, highly efficient and
precision high voltage photo-flash charger for
xenon flash applications.
The peak current is 1.5A to ensure fast
charging time. 0.5 internal power switch
minimizes the conduction loss. 50V maximum
SW operating voltage lowers transformer turns
ratio and switching loss associated with the
primary leakage inductance.
The board offers charge-ready indicator, flash
mode.
