Ceiling Fan DC Receiver Controller Problem

Hi,

I have this problem that I can't find the circuit board to identify the burnt component!
If someone has a receiver controller like this one could tell me the component reference or if someone knows the component reference for me to replace, I would be very grateful.

The brand of my fan: CREATE IKOHS

Looks like a voltage regulator, you may get an idea by measuring voltages at relevant pins.
