FAQ

What is the recommended handling for Pin 3 on the TPR6040?

Pin 3 is designated as NC (No Connect). According to the datasheet, it must be left floating or connected directly to Pin 2 (Anode/Ground).

Does the TPR6040 require external compensation capacitors for stability?

No external compensation is required. The device is designed to remain stable with any capacitive load connected to the cathode.

What is the typical reverse dynamic impedance of the TPR6040?

The typical reverse dynamic impedance is 0.3 Ω at a cathode current of 1 mA and a frequency of 120 Hz.
