Product Details
The LT80605EVKIT# (EV kit) is a proven 5V design to evaluate the LT80605 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 LT80605 is a compact, ultralow EMI emission, high efficiency, high speed synchronous monolithic step-down switching regulator that consumes only 9μA of quiescent current when the output is regulated at 5V. Top and bottom power switches, compensation components, and other necessary circuits inside the LT80605 minimize external components and simplify design.
The application circuit demonstrated in the evaluation board is suitable for a wide range of automotive, telecom, industrial, and other applications.
The LT80605 data sheet gives a complete description of the part, operation, and application information. Consult the data sheet in conjunction with this demo manual. Design files for this circuit board are available at www.analog.com.
