LM73605EVM-5V-400K: 5V @ 5A, 6 ~ 36 Vin

Summary

The LM73605EVM-5V-400K evaluation module (EVM) is a fully assembled and tested circuit for evaluating the LM73605 synchronous step-down voltage converter. The EVM operates from 6V to 36V input and provides a 5V output voltage with 5A maximum load current.

The LM73605 family of devices are easy-to-use synchronous step-down DC-DC converters capable of driving up to 5 A of load current from a supply voltage ranging from 3.5 V to 36 V. The LM73605 provide exceptional efficiency and output accuracy in a very small solution size. Peak-current-mode control is employed. Additional features such as adjustable switching frequency, synchronization to an external clock, FPWM option, power-good flag, precision enable, adjustable soft start, and tracking provide both flexible and easy-to-use solutions for a wide range of applications. Automatic frequency foldback at light load and optional external bias improve efficiency over the entire load range. The family requires few external components and has a pinout designed for simple PCB layout with optimal EMI and thermal performance. Protection features include thermal shutdown, input undervoltage lockout, cycle-by-cycle current limiting, and hiccup short-circuit protection.
