Shares essentially the same protection and robustness architecture as the v3.5, protecting the controller, MOSFETs, and switching stage, minus the v3.5's specific hot-start protection. A high-level solution for a robust, well-protected card without that added supervision feature.
This version ships in three variants, one per MELO supply architecture. Confirm your supply's architecture before buying — the wrong variant can destroy the MOSFETs and other power components.
