Analog dimming adjusts the LED current linearly; PWM dimming switches the LED on and off at a duty cycle, giving you a wider dimming ratio without color shift. The same pin handles both, so the firmware team can choose the method that fits the application — no extra pin needed. ## Switching frequency — set it where you need it The oscillator is programmable from 100 kHz to 1 MHz via a single resistor. Lower frequency cuts switching losses; higher frequency shrinks the inductor and capacitor. For EMI-sensitive designs, synchronizing to an external clock is possible — the datasheet covers the sync range. ## Package and thermal Comes in a 16-lead WFQFN with exposed pad (3 mm × 3 mm). The pad must be soldered to a copper plane for thermal relief — the junction temperature range is 0°C to 125°C, so in a high-ambient enclosure the pad is your main heat path out of the part. Surface-mount only; no through-hole option. ## Lifecycle and compliance ROHS3 compliant (lead-free). No AEC-Q100 qualification listed, so for automotive designs verify the customer's own qualification requirements against the 0°C to 125°C rating.","metaTitle":"LT3755EUD-2#PBF LED Driver Controller, 100kHz-1MHz, 16-QFN","metaDescription":"Analog Devices LT3755EUD-2#PBF DC/DC LED controller.
