Description

Datasheet LM3409, LM3409-Q1, LM3409HV , and. LM3409HV -Q1 are P-channel MOSFET ( PFET) controllers for step-down (buck) current regulators. They offer wide input The board employs a two stage design with an LM3450A flyback primary stage and an LM3409HV secondary stage. The LM3450A provides an isolated 50V Refer to AN-1953 LM3409HV Evaluation Board (SNVA390) for a detailed design procedure of the LM3409HV secondary stage and to the LM3450/A LED May 24, 2016 Automotive: LM3409-Q1, LM3409HV -Q1.
