Frequently Asked Questions
What input and output voltage ranges does the TPS54226ARGTR support in a 2 A buck application?
The TPS54226ARGTR accepts a 4.5 V to 18 V input and can produce an adjustable output down to 0.8 V, delivering up to 2 A continuous output current. This range covers 5 V, 12 V, and 15 V bus scenarios common in industrial and telecom power trees.
How does Eco-Mode improve efficiency when TPS54226ARGTR supplies a lightly loaded IoT sensor at 3.3 V output?
In Eco-Mode, the TPS54226ARGTR enters a pulse-skipping state at loads below roughly 100 mA, reducing switching losses and quiescent current. This keeps efficiency above 80% at light loads, extending battery runtime in 3.3 V sensor nodes compared to fixed-frequency designs.
Can TPS54226ARGTR operate at a switching frequency above 500 kHz and what inductor size does that allow?
Yes. The switching frequency is adjustable up to 1.5 MHz via an external resistor. At 1 MHz, a 1 µH inductor typically suffices for a 2 A, 3.3 V output from a 12 V input, significantly shrinking the footprint compared to 300 kHz designs requiring 4.7 µH or larger.
In which package does TPS54226ARGTR ship and how does it simplify thermal management?
It is available in a QFN package with an exposed thermal pad that conducts heat directly to the PCB copper plane. This allows the 2 A rated device to operate across a -40°C to 150°C junction temperature range without an external heatsink on most standard PCB layouts.
