LMR33630APAQRNXRQ1

The LMR336x0AP-Q1 regulator is an automotive-grade, easy-to-use synchronous step-down DC/DC converter that delivers excellent efficiency for demanding applications. The LMR336x0AP-Q1 supports input voltages up to 36V and can drive load currents of up to 2A or 3A. The LMR336x0AP-Q1 provides excellent light-load efficiency and output accuracy in a compact solution size. Features such as a power-good flag and precision enable facilitate flexible, easy-to-use solutions across a wide range of applications. The LMR336x0AP-Q1 automatically folds back switching frequency under light-load conditions to improve efficiency. Integration eliminates most external components, and the pinout is designed for simplified PCB layout. Protection features include thermal shutdown, input undervoltage lockout, cycle-by-cycle current limiting, and hiccup short-circuit protection. The LMR336x0AP-Q1 is available in a 12-pin 3mm×2mm VQFN package with wettable flanks.
