National P/N LM2671 - SIMPLE SWITCHER Power Converter High Efficiency 500mA Step-Down Voltage Regulator with Features
typically 50 A stand-by current. The output switch includes current limiting, as well as thermal shutdown for
full protection under fault conditions.
To simplify the LM2671 buck regulator design procedure, there exists computer design software, LM267X
Made Simple (version 6.0).
