Texas Instruments LM76002 and LM76003 are 3.5 V to 60 V, 2.5 A/3.5 A synchronous step-down regulators

Dec 19 2022 2022-12 Power Texas Instruments

Texas Instruments LM76002 and LM76003 regulators are easy to use synchronous step-down DC-DC converters capable of driving load currents up to 2.5 A (LM76002) or 3.5 A (LM76003) from input up to 60 V. The LM76002 and LM76003 provide superior efficiency and output accuracy in a very small solution size. Peak current mode control is adopted. Other functions, such as adjustable switching frequency, synchronization, FPWM option, good power mark, accurate startup, adjustable soft start, tracking, provide flexible and easy to use solutions for a wide range of applications

Texas Instruments' LM76002 and LM76003 regulators are easy to use synchronous step-down DC-DC converters capable of driving up to 2.5 A (LM76002) or 3.5 A (LM76003) load current from inputs up to 60 V. The LM76002 and LM76003 provide superior efficiency and output accuracy at very small solution sizes. Adopt peak current mode control.

Other features such as adjustable switching frequency, synchronization, FPWM options, power good mark, precision enable, adjustable soft Start, and tracking provide a flexible and easy-to-use solution for a wide range of applications. Automatic frequency folding increases efficiency under light load and optional external bias.

These devices require few external components, have a pin designed for simple PCB layouts, and have best-in-class electromagnetic interference (CISPR22) and thermal performance. Protection features include hot shutdown, input undervoltage locking, cycle current limiting and short circuit protection. The LM76002 and LM76003 devices are available in WQFN 30 pin lead-free package wettable flanks.
