The 16 V to 60 V input range covers both 12 V and 24 V automotive electrical systems. At the low end, 16 V minimum leaves headroom for a 12 V battery during cold-crank (down to ~6 V on the bus, but the regulator needs the 16 V start threshold); at the high end, 60 V max absorbs a 48 V load-dump transient without an external clamp. ## 1 A output with synchronous rectification at 2.1 MHz Rated 1 A continuous output with a synchronous rectifier — the low-side FET replaces the usual Schottky catch diode, which pulls the efficiency up at low output voltages where the diode forward drop would otherwise dominate the loss budget. Output is adjustable from 0.8 V up to 5.5 V via an external resistor divider. ## Active lifecycle — no end-of-life watch needed ROHS3 compliant — no exempt substances; fits global RoHS requirements without a waiver.","metaTitle":"ROHM BD9V100MUF-CE2 Buck Regulator, 1A, 60V Input, AEC-Q100","metaDescription":"ROHM BD9V100MUF-CE2 step-down buck regulator, 1A output, 16-60V input range, 2.1MHz switching, AEC-Q100 qualified.
