The Texas Instruments TPS54240 is an active step-down DC DC switching regulator designed for power management applications. It supports an input voltage range of 3.5V to 42V and can deliver an output current of up to 2.5A. The output voltage is adjustable from 0.8V to 39V, providing flexibility for various design requirements.
Key electrical characteristics include a typical quiescent current of 138 µA and a shutdown current of 1.3 µA, contributing to high efficiency, especially at light loads with its Pulse Skipping Eco-Mode™. The switching frequency can be set between 100 kHz and 2.5 MHz, with the option to synchronize to an external clock. It operates within a temperature range of -40°C to 125°C.
This device offers several features such as Enable, Frequency synchronization, Light Load Efficiency, Over Current Protection, Power good, Tracking, and adjustable UVLO. It utilizes current mode control and has a maximum duty cycle of 98%. The TPS54240 is available in 10-pin HVSSOP (DGQ) and 10-pin 3mm x 3mm VSON (DRC) packages, both supporting PowerPAD™ technology for enhanced thermal performance. Mounting is typically surface mount.
The TPS54240 is supported by the WEBENCH® Software Tool, aiding in design and simulation.
