产品详情

The LT80605AEVKIT# (EV kit) is a proven 5V design to evaluate the LT80605A 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 LT80605A is a compact, ultra-low 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. Top and bottom power switches, compensation components, and other necessary circuits inside the LT80605A minimize external components and simplify design. The EV kit can also evaluate the LT80605A, LT80604A, LT80605AHV, and LT80604AHV. Refer to the IC data sheet guidelines when modifying the schematic to achieve optimal performance.

The application circuit demonstrated in the evaluation board is suitable for a wide range of automotive, telecom, industrial, and other applications.

The LT80605A data sheet gives a complete description of the part, operation, and application information. Consult the data sheet in conjunction with this demo manual.
