So there is a boost converter with a flashing load that uses a buck converter. Must we guess each flasher goes at different rates and the Cap discharge buck is not constant current, constant voltage or constant power. What controls the flashing rate, the Vpeak, or each daisy chain unit.
I suppose we can guess how long these Caps will last before they fail with almost 2 A p-p ripple current. Shared by 5, hopefully equally., at least at first.... until you start daisy chaining flashers.
Something is missing in this design.
