Its supply range spans 6.5 V to 48 V, accommodating offline rectified rails and automotive battery buses alike. The part supports three topologies — SEPIC, step-down (buck), and step-up (boost) — giving the board designer flexibility to match the LED string voltage relative to the input rail without a separate converter stage. The 800 mA per-channel limit sets the maximum single-string current; for higher total lumen output, multiple strings each need their own driver or an external pass element. Switching at 300 kHz, the driver's inductor and capacitor values stay small enough for a compact footprint, but the PCB layout must keep the switching loop tight to minimise radiated emissions. Analog dimming means the LED current is controlled by a DC voltage on the dim pin — no PWM input required. This simplifies the control interface for applications where the microcontroller lacks a PWM timer or where a smooth, non-pulsed light output is needed.","metaTitle":"MAX16840ATB+T Analog Devices AC DC Offline LED Driver, 800mA","metaDescription":"Active-production offline LED driver IC, 6.5V-48V supply, 300kHz switching, analog dimming, 10-TDFN package.
