Frequently Asked Questions
What is the input and output voltage range of the TPS54326RGTT?
The TPS54326RGTT accepts an input voltage from 4.5V to 18V (nominal 12V) and delivers an adjustable output voltage from 0.76V to 5.5V, set by an external resistor divider connected to the FB pin.
What is the maximum output current of the TPS54326RGTT?
The TPS54326RGTT supports up to 3A continuous output current. Its integrated synchronous rectification with internal high-side and low-side MOSFETs enables high efficiency across the full load range without an external catch diode.
What package does the TPS54326RGTT use and what are the PCB footprint considerations?
The TPS54326RGTT comes in a 16-pin 3mm × 3mm QFN (RGT) package with an exposed thermal pad for enhanced heat dissipation. The compact footprint is suitable for high-density boards; connect the thermal pad to a ground plane with multiple vias to minimize thermal resistance.
What are typical applications for the TPS54326RGTT?
Typical applications include point-of-load regulators for FPGAs, DSPs, and microcontrollers, industrial 12V rail step-down converters, communications and networking equipment power stages, and battery-operated portable instruments requiring a regulated sub-5.5V supply.
