There are too many switching power control chips in sot23-5 package, andThe pin ordering may be different depending on the model. However, you only need to find a few key pins, such as vcc, ovp, gnd, fb, and the out pin that drives the gate of the MOS tube, and then you can easily replace it with another chip. The most critical four feet are vcc, gnd, fb, out, these four feet are right, take individual chips can be easily changed.
