Texas Instruments  LM76003QRNPTQ1

The LM76002-Q1/LM76003-Q1regulator is an easy-to-use synchronous step-down DC-DC converter capable of driving up to 2.5 A(LM76002-Q1) or 3.5 A (LM76003-Q1) ofload current from an input up to 60 V. The LM76002-Q1/LM76003-Q1 provides exceptionalefficiency and output accuracy in a very small solution size. Peak current-mode control isemployed. Additional features such as adjustable switching frequency, synchronization, FPWM option,power-good flag, precision enable, adjustable soft start, and tracking provide both flexible andeasy-to-use solutions for a wide range of applications. Automatic frequency foldback at light loadand optional external bias improve efficiency. This device requires few external components and hasa pinout designed for simple PCB layout with best-in-class EMI (CISPR25) and thermal performance.Protection features include input undervoltage lockout, thermal shutdown, cycle-by-cycle currentlimit, and short-circuit protection. The LM76002-Q1/ LM76003-Q1 device is available in the WQFN 30-pin leadless package with wettableflanks.
