A10: Always use an input line fuse to protect the module. The module must be installed in compliance with safety agency standards such as UL ANSI/UL 62368-1 and CAN/CSA C22.2 No. 62368-1.

Q11: What is the recommended input capacitance for minimizing input ripple in the APTS003A0X-SRZ?
A11: Ceramic capacitors are recommended to minimize input voltage ripple. A typical configuration includes 1x10 µF or 1x22 µF ceramic capacitors at the input.

Q12: How can I program the output voltage using an external resistor in the APTS003A0X-SRZ?
A12: The output voltage can be programmed using the formula: Rtrim​=(Vo​−0.591)5.91​ where Rtrim​ is in kΩ and Vo​ is the desired output voltage.

Q13: What is the maximum recommended external capacitance for stable operation in the APTS003A0X-SRZ?
A13: The maximum recommended external capacitance is 1000 µF with an ESR ≥ 0.15 mΩ when using the Tunable Loop™, and 3000 µF with an ESR ≥ 10 mΩ.

Q14: How do I use the remote sense feature in the APTS003A0X-SRZ?
A14: The remote sense feature minimizes distribution losses by regulating the voltage at the SENSE pin. Connect the SENSE pin to the load point to ensure accurate voltage regulation.

Q15: What is the Power Good (PGOOD) signal and how is it used in the APTS003A0X-SRZ?
A15: The PGOOD signal indicates that the output voltage is within regulation limits. It is an open-drain output and should be connected to a 5VDC source through a pull-up resistor (suggested value 100KΩ).

Q16: What is the MTBF (Mean Time Between Failures) of the APTS003A0X-SRZ module?
A16: The calculated MTBF for the APTS version is 15,694,689 hours.

Q17: What are the available On/Off logic options for the APTS003A0X-SRZ?
A17: Two options are available: Positive Logic (device code suffix “4”) and Negative Logic (no suffix). Positive Logic turns the module ON during a logic High and OFF during a logic Low. Negative Logic does the opposite.
