LM3481MMX/NOPB +BOM

The LM3481MMX/NOPB offers efficient voltage conversion for various electronic devices requiring a higher output voltage

LM3481MMX/NOPB General Description

Safety is a priority with the LM3481MMX/NOPB, as it comes with built-in protection features including thermal shutdown, short-circuit protection, and overvoltage protection. Additionally, its power-saving shutdown mode reduces the total supply current to 5 µA and enables power supply sequencing. The internal soft-start feature limits the inrush current at start-up, contributing to a smooth and controlled operation
