Dear Sir
ReplyDeletemight I replace P301-16 by P301-40? are they have any different?
Dear Hocham,
DeleteThank you for your question!
While both the P301-16 and P301-40 belong to the same family of power management ICs used in LCD/LED panels, they are generally not directly interchangeable without careful verification.
Here is why:
Pinout & Configuration: Even small suffix differences (-16 vs -40) often indicate variations in internal voltage regulation, default delay timings, or feedback configurations designed for specific panel resolutions and manufacturer requirements.
Voltage & Output Parameters: Always cross-check the datasheet for both ICs, especially the VGH, VGL, and AVDD output levels, along with the PWM switching frequencies.
If the pinout mapping and essential voltage specifications match your original T-Con board schematic, it might work, but it is always safest to match the exact part number to avoid panel protection mode or damage. Let me know which specific panel model you are working on!
Best regards,
M.A. Mustafa
