Texas Instruments  LM73606RNPT

The LM73605/LM73606 family of devices are easy-to-use synchronousstep-down DC-DC converters capable of driving up to 5 A (LM73605) or 6 A(LM73606) of load currentfrom a supply voltage ranging from 3.5 V to 36 V. The LM73605/LM73606 provideexceptional efficiency and output accuracy in a very small solution size. Peak current-mode controlis employed. Additional features such as adjustable switching frequency, synchronization to anexternal clock, FPWM option, power-good flag, precision enable, adjustable soft start, and trackingprovide both flexible and easy-to-use solutions for a wide range of applications. Automaticfrequency foldback at light load and optional external bias improve efficiency over the entire loadrange. The family requires few external components and has a pinout designed for simple PCB layoutwith optimal EMI and thermal performance. Protection features include thermal shutdown, inputundervoltage lockout, cycle-by-cycle current limiting, and hiccup short-circuit protection. TheLM73605 and LM73606 devices are pin-to-pin compatible for easy current scaling.
