BOARD LAYOUT
The high voltage operation of the LT3420/LT3420-1
demands careful attention to board layout. You will not
get advertised performance with careless layout. Fig-
ure11 shows the recommended component placement.
Keep the area for the high voltage end of the secondary
as small as possible. Note the larger than minimum
spacing for all high voltage nodes. This is necessary to
meet the breakdown specifications for the circuit board.
If the Photoflash capacitor is placed far from the LT3420/
LT3420-1 circuit, place a small (20nF-50nF) ceramic
capacitor with sufficient voltage rating close to the part.
This insures adequate bypassing. Remember that
LETHAL VOLTAGES ARE PRESENT
in this circuit. Use
caution when working with the circuit.
