Ps42419ha Schematic Top Better

This review is purely speculative. For an accurate assessment, more context or direct access to the schematic and its performance data would be necessary.

Connect the rectified mains output (e.g., from a diode bridge + 450V electrolytic capacitor) across P and N. Ensure the capacitor is rated for at least 400V and has low ESR. ps42419ha schematic top
