Description for the LM73605
The LM73605 and LM73606 family ofdevices are easy-to-use synchronous step-down DC/DC converters capable of driving up to 5 Aor 6 A of load currentfrom a supply voltage ranging from 3.5 V to 36 V. The LM73605 andLM73606 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, power-good flag, precision enable,adjustablesoft start, and tracking provide both flexible andeasy-to-use solutions for a wide range of applications. Automatic frequency foldback at lightloadimproves efficiency over the entire load range. Protectionfeatures include thermal shutdown, cycle-by-cycle current limiting, and short-circuitprotection. The devices are pin-to-pin compatible foreasy current scaling. The new product, LM61460-Q1, offers higher efficiency, lowerstand-by quiescent current, and improved EMI performance.
