It integrates the switching FET internally, so the BOM stays tight — just the inductor, input/output caps, and a few passives. Switching at 370 kHz keeps the magnetics small enough for a compact PCB layout, and the PWM dimming input gives you direct LED brightness control without an external DAC. ## Key ratings for the BOM decision Input range spans 4.75 V to 45 V. Single 1.8 A output channel. ## Lifecycle and sourcing For a BOM freeze or a PCN watch, this part is currently stable — no near-term obsolescence risk.","metaTitle":"TLD5085EJ LITIX™ DC-DC Buck Regulator, 370 kHz, 1.8 A","metaDescription":"Infineon TLD5085EJ LITIX™ DC-DC step-down regulator, 370 kHz switching, 1.8 A output, PWM dimming, -40 to 150°C.
