My project uses Vin 9 ... 28 V. Lead acid battery 6 cells .. Charge current 5 A. Load current 10A.
I am faced with the problem of strong heating of the coil with a load of more than 3 A, the coil heats up> 70 degrees. The coil used is such a SRP1770C-4R7M. All mosfet Sir664.
Could it be caused by incorrect compensation work? And can I calculate the denominations of the compensation components for the LTC4020 in the LTPowerCAD program using a project for example for the LTC3780, how true will this be?
