Frequently Asked Questions
What is the input voltage range of the TPS54561-Q1?
The TPS54561-Q1 supports an input voltage range of 4.5V to 60V, making it suitable for automotive 12V and 24V systems as well as industrial applications that experience wide supply voltage variations including load dump events.
What is the maximum output current of the TPS54561-Q1?
The TPS54561-Q1 can deliver up to 5A continuous output current. The integrated high-side MOSFET with low RDS(on) helps maintain efficiency at full load while minimizing heat dissipation in the design.
What does Eco-mode do in the TPS54561-Q1?
Eco-mode is a light-load efficiency enhancement feature that reduces switching losses by entering pulse-skipping operation when the output load current drops below a threshold, significantly improving efficiency and reducing quiescent current draw in standby or low-power conditions.
Is the TPS54561-Q1 AEC-Q100 qualified for automotive use?
Yes, the TPS54561-Q1 is AEC-Q100 qualified, meaning it meets stringent automotive reliability standards for temperature cycling, humidity, and electrostatic discharge, making it suitable for use in automotive electronics such as ADAS, body control modules, and infotainment systems.
What package is the TPS54561-Q1 available in?
The TPS54561-Q1 is available in a Small Outline No-lead (SON) package, which offers a compact footprint, excellent thermal performance through exposed pad, and is well-suited for space-constrained PCB designs requiring surface-mount assembly.
