DC2522A - LT8609S Demo Board | Silent Switcher 2 Buck, 5.5V ≤ VIN ≤ 42V, VOUT = 5V @ 2A, fSW = 2MH

Demonstration circuit 2522A is a 42V, 2A/3A peak micropower synchronous step-down regulator featuring the LT®8609S. The demo board is designed for 5V output from a 5.5V to 42V input. The wide input range allows a variety of input sources, such as automotive batteries and industrial supplies. The LT8609S is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that consumes only 2.5μA of quiescent current when output is regulated at 5V. Top and bottom power switches, compensation components and other necessary circuits are inside of the LT8609S to minimize external components and simplify design.
