Introduction

AI Translation

The LM76002/LM76003 regulator is an easy-to-use synchronous step-down DC-DC converter capable of driving up to 2.5 A (LM76002) or 3.5 A (LM76003) of load current from an input up to 60 V. The LM76002/LM76003 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 (CISPR22) and thermal performance. Protection features include input undervoltage lockout, thermal shutdown, cycleby-cycle current limit, and short-circuit protection. The LM76002/LM76003 device is available in the WQFN 30-pin leadless package with wettable flanks.
