DEMO MANUAL DC1935A
LT4363-1/LT4363-2
High Voltage Surge Stopper
with Current Limit
DESCRIPTION
Demonstration Circuit 1935A showcases the LT
®
4363 surge
stopper in a 12V, 2A application. Inputs of up to 80VDC
and 1ms transients of up to 250V are limited to 16.3V
at the output. The MOSFET is protected against output
overloads by current limiting. Sustained overvoltage or
overcurrent conditions cause the LT4363 to turn off after a
timer delay. The LT4363-1 latches off and is reset by pulling
SHDN
low for at least 100μs. The LT4363-2 automatically
retries after a cool down delay; retry is inhibited if OV is
higher than 1.275V.
By removing 0Ω jumpers R1C and R4C, the operation may
be modified for 28V systems with an output regulation
point of 34.6V in overvoltage conditions.
