What are the key features of TPS54140ADRCT?
- Wide 3.5V to 42V input voltage range supporting industrial, automotive, and telecommunications power rails
- 1.5A output current with current-mode PWM control for fast transient response and inherent cycle-by-cycle current limiting
- Compact 10-pin VSON package (JESD-30 code S-PDSO-N10) with lead-free e4 compliance for high-density board designs
What is TPS54140ADRCT used for?
The TPS54140ADRCT is designed for step-down DC-DC conversion in industrial automation equipment, telecom infrastructure, and automotive electronics where wide input voltage variation is common. Its current-mode control architecture delivers excellent load transient response and simplifies compensation design for fast-switching power supplies. The 42V maximum input makes it ideal for 24V and 36V industrial bus systems requiring efficient point-of-load regulation.
