It operates as a constant-current, constant-voltage controller supporting SEPIC, step-down (buck), and step-up (boost) topologies, so the same part can serve a boost string for high-bay lighting or a buck string for an automotive taillight. ## Switching frequency and dimming flexibility The oscillator runs from 90 kHz to 1.24 MHz, set by a single resistor. At the low end, switching losses drop and efficiency climbs for heavy loads; at the high end, the inductor and output capacitor shrink, which matters when board area is tight in an automotive module. Dimming is handled both by a PWM input (for high-ratio, flicker-free dimming down to low duty cycles) and an analog control pin (for continuous brightness adjustment). This dual approach means the same controller can serve a dashboard backlight that needs smooth analog dimming and a daytime-running light that switches on/off with a PWM signal from the body controller. ## Supply and output voltage reach Input supply range is 2.5 V to 38.5 V, covering a single lithium-ion cell at the low end and a 24 V truck battery at the high end. The output can go up to 60 V, which is enough for a string of 15 to 18 white LEDs in boost mode without stacking multiple drivers. ## Package and thermal interface Housed in a 28-lead WFQFN with an exposed pad (4 mm × 5 mm), the part relies on the pad for heat sinking. ## Lifecycle and compliance It is also RoHS3 compliant, so no exemption-based paperwork is needed for EU or California markets.","metaTitle":"LT3762HUFD#PBF LED Driver Controller, 60V, 28-QFN","metaDescription":"Analog Devices LT3762HUFD#PBF DC DC LED driver controller.
