The power chip wd09a cannot be replaced by Vip22 directly, because their electrical parameters and functions are different. Although they are all power management chips, there are differences in their input voltage range, output voltage range, maximum output current, protection functions, and so on.
If you directly replace wd09a with Vip22, it may lead to circuit instability, insufficient power output, overcurrent protection failure and other problems, and even damage other electronic components. Therefore, when replacing the power chip, it is necessary to carefully analyze the circuit design and chip specifications and select a suitable alternative.
According to the information I found, WD09A and VIP22 are two different power management chips with different specifications and functions. Therefore, the WD09A chip cannot be directly replaced with VIP22, and their pins and functional configurations may not match, which may cause the circuit to be unstable or not work.

When a power management chip needs to be replaced, it is best to use a replacement that has similar specifications and features to the original chip. If you are unsure how to choose an appropriate alternative chip, it is recommended to consult an electronic component specialist or contact the manufacturer for the right advice and guidance.
