The LT8650S is a dual 4A, 42V input synchronous step-down switching regulator. It’s unique Silent Switcher2 architecture uses four internal input capacitors as well as two internal BST and a single INTVCC capacitor to minimize the area of the hot loops. Combined with very well controlled switching edges and an internal construction using copper pillars ...
