Hi,
I want to develop a power supply circuit using the LT8357.
The output voltage is 5Vdc with a maximum output current of 2.5A.
The input voltage is always above 8V but during start-up it could drop to 3V for about 20msec.
So I was thinking of using the LT8357 in sepic configuration even if 99% of the time it will always work in buck mode.
Is there an excel to perform all the necessary calculations?
Regards
Robert
Hi Jhun
I saw that I could use the LTpowercad tool to calculate the circuit.
Unfortunately, it only allows me to use it for "SEPIC not L-Couperd".
If I select "SEPIC Couped L" I get this error.
is there a solution?
I have already tried to update with SYNC/RELEASE.
