Frequently Asked Questions
What is the input and output voltage range of the TPS54310PWP?
The TPS54310PWP accepts an input voltage from 3V to 6V (nominal 5.5V) and supports an adjustable output voltage down to a minimum of 0.9V, making it suitable for generating 1.0V, 1.2V, 1.8V, and 3.3V rails from a 5V supply.
What switching frequency does the TPS54310PWP operate at, and why does it matter?
The TPS54310PWP switches at up to 762kHz. A higher switching frequency reduces the size of the required external inductor and output capacitors, enabling a more compact PCB layout and faster transient response for dynamic loads.
What package does the TPS54310PWP come in, and what are its thermal characteristics?
The TPS54310PWP is housed in a 20-pin HTSSOP with an exposed thermal pad (EP). The exposed pad significantly reduces junction-to-board thermal resistance, allowing the device to deliver its full 3A output current across a wide temperature range in typical PCB designs.
What are common applications for the TPS54310PWP?
Typical applications include point-of-load regulators in telecom line cards, industrial PLCs, DSP and FPGA core supplies, set-top boxes, and portable test instruments where a regulated sub-1V to 3.3V output must be derived from a 5V bus with high efficiency.
Is the TPS54310PWP RoHS compliant?
Yes, the TPS54310PWP carries a Pb-free (RoHS) designation (JESD-609 code e4), confirming it meets halogen-free and lead-free soldering requirements for environmentally compliant manufacturing.
