The 85% maximum duty cycle supports moderate step-down ratios without pulse-skipping. Control features include an enable pin for sequencing and a power-good output for rail monitoring. The part is rated for the industrial temperature range of -40°C to 85°C, covering most factory-floor and outdoor telecom enclosures. ## Package and PCB considerations Mounting is surface-mount only. The shipping options include Tape & Reel (TR) for automated pick-and-place and Cut Tape (CT) for prototype or low-volume builds. ## Sourcing and lifecycle The TPS40193DRCR is listed as Active in production with ROHS3 compliance.","metaTitle":"TPS40193DRCR Buck Controller, 300kHz, 10-VSON","metaDescription":"TI TPS40193DRCR step-down buck controller, 4.5V-18V input, 300kHz fixed frequency, synchronous rectification, 10-VSON (3x3mm) package.
