Texas Instruments  LM76002RNPT

The LM76002/LM76003 regulator is an easy-to-use synchronous step-down DC-DC convertercapable of driving up to 2.5 A (LM76002) or 3.5 A (LM76003) of load current from an input up to 60V. The LM76002/LM76003 provides exceptional efficiency and output accuracy in a very small solutionsize. Peak current-mode control is employed. Additional features such as adjustable switchingfrequency, synchronization, 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. Thisdevice requires few external components and has a pinout designed for simple PCB layout withbest-in-class EMI (CISPR22) and thermal performance. Protection features include thermal shutdown,input undervoltage lockout, cycle-by-cycle current limit, and short-circuit protection. TheLM76002/LM76003 device is available in the WQFN
30-pin leadless package with wettable flanks.
