BP2863 is an efficient step-down regulator chip with multiple protection functions for a wide range of power management applications. Its pin functions are as follows:
VIN: Input voltage pin, connected to the positive terminal of the input power supply.
GND: Ground pin that connects the input power negative to the output negative.
FB: Feedback pin that connects the feedback resistance to the output voltage.
EN: Enable pin, high level active, control the on-off state of the chip.
SS: Soft start pin, connected capacitor to achieve soft start function.
PG: Good power supply pin, high level when the output voltage is normal.
VOUT: Output voltage pin, connected to the output load.
Among them, VIN, GND and VOUT are the basic pins of BP2863, which are used to connect the input power supply and the output load. The FB pin is used to feedback the output voltage to the internal chip for control, the EN pin is used to control the switching state of the chip, the SS pin is used to achieve the soft start function, and the PG pin is used to indicate whether the output voltage is normal. The specific functions and usage of these pins can be found in the BP2863 data book. I hope this information is helpful to you!
