TL3842P can be replaced by UC3482 or KA3842A. The pin functions of the TL3842P power management chip are as follows:
① is the output end of the internal error amplifier;
The foot is the reverse input end of the internal error amplifier; The RC network between the ① and ② feet is used to determine the gain and frequency of the amplifier; ⑤ The pin is the grounding terminal.
