Dimming is dual-mode: analog current adjust and PWM duty-cycle control, both present on the same pin — you can blend them or switch between them without changing the board layout. ## Switching frequency and inductor sizing The oscillator runs from 100 kHz to 1 MHz, set by a single resistor to ground. A 200 kHz design uses a larger inductor but lower switching losses; 1 MHz shrinks the magnetics but demands a faster gate driver and careful PCB layout to keep the switch-node ringing under control. Because the controller lacks an internal switch, the switching frequency choice directly sets the FET gate charge losses — a 1 MHz design with a 10 nC gate FET dissipates 10 mW just in gate drive, which is fine in the 16-MSOP-EP package's thermal pad but worth budgeting.","metaTitle":"LT3761IMSE-1#PBF LED Driver Controller, 60V, 16-MSOP-EP","metaDescription":"LT3761IMSE-1#PBF DC DC controller for LED strings.
