5aarbp Power chip pin function?

5AARBP power chip is a device for power management, mainly used to provide power stability and protection functions.
The following is the pin function of the common 5AARBP power supply chip:
1. VCC (power input) : Access the positive terminal of the power supply, usually the DC voltage input of the power supply.
2. GND (ground) : The negative terminal connected to the power supply, usually the ground cable of the power supply.
3. VIN (Input voltage) : input of an external power supply (such as a battery).
4. VOUT (output voltage) : The output voltage supplied to the external circuit.
5.EN (Enable) : Used to control the on-off state of the chip or some specific function.
6.FB (Feedback) : Feedback information used to monitor the chip output voltage, usually connected to a resistor voltage division network.
7.SS (Soft boot) : Used to control the startup time and mode of the chip.
8.PG (good power) : used to indicate whether the output voltage of the chip reaches the set range.
9. PGND (power ground) : connected to GND for the power loop of the chip.
10. BST (Boost inductor) : Used to connect external inductors, usually used in boost conversion circuits.
11.SW (switch) : The switch control pin of the chip, which controls the switch connected to the input and output of the chip.
12.CS (Current sampling) : Used to measure the output current, usually connected to a resistor. REF (Reference voltage) : The reference voltage provided to the chip, usually a fixed voltage value.
It should be noted that different 5AARBP power chips may have different pin functions and configurations, and the above only lists the common pin functions. Specific functions and configurations can be obtained by referring to the data manual or specifications of the chip.


5AARBP power chip is a high-efficiency, low-voltage difference, output current up to 5A power management chip, its pin functions include input power, ground, output power, regulation voltage, amplifier input, amplifier output, regulation voltage filtering, output current limit and thermal shutdown.

Among them, the input power and ground pins are used to access the external power supply, the output power pin provides the output voltage for the chip, the regulating voltage pin is used to adjust the output voltage, the amplifier input and output pins are used to control the gain and stability of the amplifier inside the chip, and the regulating voltage filter pin is used to improve the stability of the regulating voltage. Output current limiting and thermal shutdown pins are used to protect the chip and external circuits.


5AARB power supply chip is a kind of power management chip with high efficiency and high stability. It has a variety of pin functions, including input voltage, output voltage, ground, control signal and so on. Where, the VIN is the input voltage pin, usually connected to a power supply such as a power adapter or battery.

VOUT is the output voltage pin that connects to the load circuit to provide a stable output voltage.

EN is the control pin used to control the switch of the chip to start and stop or the output voltage.

PG is a good power supply pin, used to monitor whether the output voltage is normal. In addition, there are several auxiliary pins, such as VCC, GND, etc. These pins have different functions, but work together to ensure the normal operation of the chip and the stability of the output voltage.
