Frequently Asked Questions

What is the operating frequency and efficiency range?

The device operates at a 275 kHz switching frequency. Efficiency ranges from 81%-95% depending on load conditions.

Can this converter handle specific battery types?

Yes, it features true current limit for Li-ion battery compatibility.

How does the TEA1207T switch between up and down modes?

The U/D pin selects the mode: active LOW for up conversion and HIGH for down conversion.

What guarantees efficiency during short load peaks and low voltage operation?

The functional description confirms that accurate current limiting and the Undervoltage Lockout circuit ensure efficient behavior even during short load peaks.
