The answer is as follows: The 6853 chip power supply chip is an integrated circuit chip with the following pin functions:
1. VIN: Input voltage end, usually DC power supply.
2. VOUT: Output voltage end, usually stable DC voltage.
3. GND: The ground end is used to connect the negative terminal of the power supply to the negative terminal of the output load.
4. EN: Enable end, used to control the on-off state of the chip.
5. FB: feedback terminal, used to connect feedback resistance, control output voltage stability.
6. COMP: compensation terminal, used to connect the compensation element, improve the output voltage response speed.
7. SS: Soft starting terminal, used to control the rising speed of the output voltage, to avoid the phenomenon of overcurrent when starting.
8. PG: Power supply detection terminal, used to detect whether the input voltage is stable to ensure that the output voltage is stable.
