DC1749A - Schematic5/29/2012
This evaluation board is obsolete and no longer recommended.
Demonstration circuit 1749A is a 42V, 2.5A micropower synchronous step-down regulator featuring the LT8610. The LT8610 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 3.3V. Top and bottom power switches, compensation components and other necessary circuits are inside of the LT8610 to minimize external components and simplify design.
