Product Details

Demonstration Circuit 2564A is a 42V, 0.35A micropower synchronous step-down regulator featuring the LT8606. 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 LT8606 is a compact, high efficiency, high speed synchronous monolithic step-down switching regulator that consumes less than 3μA of quiescent current when output is regulated at 5V. Top and bottom power switches, compensation components and other necessary circuits are inside of the LT8606 to minimize external components and simplify design.
