Description
The TPS54231DR is a high-performance, asynchronous step-down (buck) converter designed to provide a reliable, adjustable output from a wide input voltage range of 3.5V to 28V. Featuring an integrated high-side MOSFET, this device excels in efficiency and ease of use. It utilizes pulse-width modulation (PWM) at a fixed 570kHz switching frequency, which allows for smaller external inductor and capacitor footprints, saving critical space on your PCB.
A standout feature of the TPS54231 is its “Eco-mode,” which significantly boosts light-load efficiency, making it an ideal choice for battery-powered systems or devices that spend considerable time in standby. With integrated features like cycle-by-cycle current limiting, thermal shutdown, and over-voltage transient protection, the TPS54231DR is engineered to provide a robust, fault-tolerant power solution for industrial, automotive, and consumer applications.
