Its 4.5 V to 110 V supply range covers automotive cold-crank and load-dump transients without an external clamp — the internal bias regulator handles the full swing. Switching frequency is programmable from 100 kHz to 1 MHz, letting you trade inductor size against efficiency: lower frequency reduces switching losses, higher frequency shrinks the magnetics. ## Dimming and output control Supports both analog and PWM dimming — the PWM input accepts an external logic signal for wide-range, linear dimming down to zero current, while the analog control pin sets a DC current level. Single output, no internal switch — the controller drives an external N-channel MOSFET, so the output current ceiling depends on the external FET and inductor choice, not the IC itself. ## Lifecycle and compliance Supplied in tube packaging. The tape-and-reel variant (LT3795EFE#TRPBF) is available for pick-and-place volume; the die and electrical specs are identical.","metaTitle":"LT3795EFE#PBF DC DC Controller, 4.5-110V, 28-TSSOP","metaDescription":"Active LT3795EFE#PBF DC DC LED driver controller from Analog Devices. 4.5-110V supply, 100kHz-1MHz, PWM/analog dimming. 28-TSSOP EP.
