Frequently Asked Questions
What is the input voltage range of the TPS54283PWP?
The TPS54283PWP accepts an input voltage from 4.5V to 28V, with a nominal operating point of 12V. This wide range makes it compatible with standard 5V, 12V, and 24V industrial and telecom power rails.
What output voltage and current can the TPS54283PWP deliver?
Each channel of the TPS54283PWP can deliver up to 2A of output current. The output voltage is adjustable from 0.8V to 25.2V, allowing it to power a wide variety of digital and analog loads in the same system.
What are typical applications for the TPS54283PWP?
The TPS54283PWP is commonly used in industrial control systems, network equipment, embedded processors, and telecom power supplies. Its dual-channel design is especially useful for generating multiple supply rails—such as 1.0V core and 3.3V I/O—from a single intermediate bus voltage.
What package does the TPS54283PWP use, and are there thermal considerations?
The TPS54283PWP comes in a 14-Pin HTSSOP package with an exposed thermal pad (EP). The exposed pad significantly reduces junction-to-board thermal resistance, enabling reliable operation at full load in space-constrained PCB layouts.
Is there a lead-free version of the TPS54283PWP available?
Yes, the TPS54283PWP is Pb-free and RoHS compliant, as indicated by the Pbfree Code: Yes specification. It is fully compatible with modern lead-free soldering processes used in industrial and consumer electronics manufacturing.
