BD9V100MUF-EVK-001: 5V @ 1A, 16 ~ 60V in, Automotive

Summary

BD9V100MUF-EVK-001 is a current mode synchronous buck converter that uses high voltage rated POWER MOSFETs. It features a wide range input voltage range of 16V to 60V and utilizes a very short minimum pulse width (down to 20ns) which enables direct conversion from 60V power supply to 3.3V at 2.1MHz operation.

Note that this EVK uses some additional components when compared against the reference application circuit (primarily the additional filter and capacitors on the input side). These were added to this EVK to pass the CISPR22 radiated emissions test. If this is not a concern for your application, these external components may be omitted from your final design to required board space and external components.
