It integrates the switching FET internally, so the bill of materials stays compact — just the inductor, input/output caps, and a few resistors. The 600 kHz switching frequency keeps the inductor physically small, which matters when board space is tight in an LED display or IR illuminator module. ## 28 V ceiling and PWM dimming Output voltage goes up to 28 V, matching the supply maximum — that covers a string of eight to ten series LEDs in a typical lighting fixture or an IR flood for night-vision cameras. Dimming is via PWM, which means you can vary brightness by modulating the enable pin with a logic-level signal from a microcontroller or sensor; no external DAC needed. The 4.5 V minimum supply lets it run off a standard 5 V rail or a 12 V automotive bus with headroom. ## Thermal range and package The TSOT-23-6 package is a thin SOT-23 footprint, surface-mount only, so it reflows with the rest of the board in a standard lead-free profile. No exposed pad to worry about for thermal dissipation at 1.5 A continuous, but the board copper plane should be generous. ## Lifecycle and compliance ROHS3 compliant, so it clears the current European and global restrictions on hazardous substances. For a production BOM line that needs a buck LED driver with a firm supply horizon, this part is a low-risk pick.","metaTitle":"TPS54201DDCR Buck LED Driver, 1.5A, 600kHz, TSOT-23-6","metaDescription":"Texas Instruments TPS54201DDCR DC DC regulator, buck topology, 1.5A output, 600kHz switching, PWM dimming, 28V max, -40°C to 125°C.
