Frequently Asked Questions
What is the input voltage range of the TPS54240DGQ?
The TPS54240DGQ accepts an input voltage from 3.5V to 42V, with a nominal operating voltage of 12V. This wide range makes it suitable for industrial, automotive, and telecom applications where supply rails may vary significantly.
What is the maximum output current of the TPS54240DGQ?
The TPS54240DGQ can deliver up to 2A of continuous output current. Its current-mode PWM control enables precise cycle-by-cycle current limiting, protecting downstream components during overload conditions.
What package does the TPS54240DGQ use, and what are its dimensions?
The TPS54240DGQ comes in a 10-pin MSOP (S-PDSO-G10) small-outline package, which is lead-free (Pb-free). This compact footprint minimizes PCB area while maintaining thermal performance for up to 2A load applications.
What are common applications for the TPS54240DGQ?
Common applications include industrial automation (PLCs, sensor power supplies), automotive electronics, telecom line cards, and point-of-load regulators in embedded systems. Its 42V rating and wide input range make it especially suited for harsh-environment or battery-powered designs.
Are there pin-compatible or drop-in alternatives to the TPS54240DGQ?
The TPS54240DGQ is part of Texas Instruments' TPS5424x family. Close alternatives include the TPS54240 (different package options) and the TPS54231, which offers similar current-mode step-down regulation with comparable input voltage ratings. Always verify pinout and compensation network compatibility before substituting.
