Frequently Asked Questions
How much input voltage headroom does the TPS54061DRBR provide for unregulated bus rails?
The TPS54061DRBR accepts an input voltage range of 3.5V to 60V, giving designers enough headroom to regulate directly from unfiltered 12V, 24V, or 48V industrial bus rails without additional pre-regulation circuitry, while delivering up to 200mA of continuous output current.
What thermal limits should engineers plan around when laying out this converter?
This device is rated for a junction temperature range of -40°C to 150°C, so PCB designers should ensure adequate copper area and thermal vias to keep the junction within that window under full 200mA load in enclosed industrial or automotive housings.
Why choose the Eco-mode switching scheme for battery-powered designs?
Eco-mode pulse-skipping lets the TPS54061DRBR maintain high efficiency at light loads by switching at up to 2.5MHz under heavy load and reducing switching activity as load current drops toward zero, which extends battery runtime in remote sensor and metering applications.
