LT80603EVKIT#

LT80603EVKIT# is a proven 5V design to evaluate the LT80603 synchronous step-down Silent Switcher®. The EV kit is designed for a 5V output. The wide input range up to 65V allows a variety of input sources, such as automotive batteries and industrial supplies. The LT80603 is a compact, ultralow electromagnetic interference (EMI) emission, high efficiency, high-speed synchronous monolithic step-down switching regulator that consumes only 8μA of quiescent current when the output is regulated at 5V. The top and bottom power switches, compensation components, and other necessary circuits within the LT80603 minimize the need for external components and simplify the design. The EV kit can also evaluate the LT80602, LT80603A, LT80603HV, LT80602HV, and LT80603AHV. The application circuit demonstrated in the evaluation board is suitable for a wide range of automotive, telecom, industrial, and other applications.
