Linear Technology Corporation, a subsidiary of Analog Devices, Inc. (ADI), introduced the LT8609S, a 2A (3A peak), 42V input synchronous step-down switching regulator. Its unique Silent Switcher® 2 architecture utilizes two internal input capacitors and internal BST and INTVCC capacitors to minimize thermal loop area. The LT8609S is designed to significantly reduce EMI/EMC emissions due to the extremely well-controlled switching edges, with an internal ground plane and copper posts instead of bond wires.
