That topology flexibility (SEPIC, step-down, step-up) means one qualified controller covers a 27 V output rail for a backlight bar or a boost stage for a multi-string automotive tail-light assembly. Dimming is dual-mode: analog current adjust or PWM, selectable without a second IC. The 100 kHz to 1 MHz switching range lets you trade inductor size against efficiency; 1 MHz keeps the magnetics small for space-constrained lamp modules. ## Temperature grade and environment Rated -40°C to 125°C ambient, this controller is built for automotive exterior lighting and industrial LED arrays that see engine-bay or outdoor thermal cycling. ## Sourcing and lifecycle No end-of-life notice on record. The part is ROHS3 compliant. No direct replacement or second-source alternate is listed in the manufacturer's cross-reference.","metaTitle":"MAX16834ATP+ LED Driver Controller, Buck/Boost/SEPIC","metaDescription":"MAX16834ATP+ is an active LED driver DC-DC controller from Analog Devices.
