It integrates the switching FET internally and supports both analog and PWM dimming methods, giving the designer two options for brightness control without external dimming components. ## 9-35V input range, 50kHz-2MHz switching Input supply range spans 9V minimum to 35V maximum — wide enough to cover nominal 12V and 24V automotive or industrial rails with margin for transients. The switching frequency is programmable from 50 kHz up to 2 MHz, so the designer can trade inductor size against efficiency: lower frequencies reduce switching losses, higher frequencies shrink the magnetics footprint. Operating temperature range covers -40°C to 105°C, which qualifies the part for under-hood automotive and outdoor industrial environments where ambient heat is a factor. ## Active production, RoHS3 compliant The part is also RoHS3 compliant, which means it meets the latest EU restriction of hazardous substances directive without exemptions — no lead, mercury, cadmium, or phthalates above the threshold limits.","metaTitle":"BD9408FV-E2 ROHM Boost LED Driver, 35V, PWM/Analog Dim","metaDescription":"BD9408FV-E2 ROHM active-production boost LED driver, 9-35V input, 50kHz-2MHz switching, analog+PWM dimming, -40 to 105°C.
