There is a problem with the EVM (DC2575A) circuit.
What is the function of D5 (PMEG3010EB) in the circuit?
Is it necessary?
I'm Lonnie Kim DFAE in Sheenbang(Korea)
I have some question about LT8391A.
1. What different with LT8391 and LT8391A?
2. How much wattage for LED control?
LT8391 may control about 100Watt. Is same to LT8391A?
Thanks for your reply.
I have one more question, do you have LT8391A+LT3965 transient response ?
The LT3518 is not designed for short-circuit protection.
More recent ICs such as the LT3922, LT3795, LT3762, LT3932, LT8391A and other LED drivers now have the short-circuit protection which you are looking for.
I hope this helps,
I have a custom PCB that just arrived and am testing the LED driver based on the LT8391A. The design is mostly sourced from the DC2345A reference design, however, a number of components were swapped due to the voltage ratings and needs…
I see that you are looking for an LED driver with these specs...
input voltage from 3v to 18v and a 12v and 2.1A output
This clearly requires one form or another of a buck-boost topology.
The LT8391 is a great buck-boost to use (with…
I would like to parallel two LT8930A controllers and synchronize the oscillators with 180° phase offset. Is it possible to do this without an external clock? If so, how?
I purchased a DC2345A evaluation board for the LT8391A. I modified the board to output 40V by changing R6 to 25KOhms and 5.5A by modifying the sense resistor to 18 mOhms. This works great when running the LEDs at 100% duty cycle.
