Introduction

AI Translation

The LM73605/LM73606 family of devices are easy-to-use synchronous step-down DC-DC converters capable of driving up to 5 A (LM73605) or 6 A (LM73606) of load current from a supply voltage ranging from 3.5 V to 36 V. The LM73605/LM73606 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. The LM73605 and LM73606 devices are pin-to-pin compatible for easy current scaling.
