The LM76002-Q1/LM76003-Q1 regulator 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) of load current from an input up to 60 V. The LM76002-Q1/LM76003-Q1 provides 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, 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. This device requires few external components and has a 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 current limit, and short-circuit protection. The LM76002-Q1/LM76003-Q1 device is available in the WQFN 30-pin leadless package with wettable flanks.
