5A2R power supply chips typically have the following pin functions:
1. VIN: Input voltage pin that receives input voltage from an external power supply.
2. VOUT: Output voltage pin that provides stable output voltage to other circuits or devices.
3. GND: Ground pin that connects to the power supply.
4.EN: Enables the pin to control the on-off function of the chip. When the EN is pulled up, the chip starts to work; When the EN is pulled down, the chip stops working.
5.PG: Power good pin, used to indicate the working status of the chip. When the PG pin outputs high voltage, it indicates that the chip is working normally.
6.FB: Feedback pin used to adjust the stability of the output voltage. Adjust the value of the output voltage by connecting an external resistor or capacitor.
7.CIN: Input capacitance pin to smooth input voltage and provide current reserve.
8. COUT: Output capacitance pin, used to smooth the output voltage and provide current reserve.
Please note that different models of 5A2R power chip pin functions may vary, the above are common pin functions.
The functions of each pin of the 5a2r six-pin power chip are as follows: Pin 1: Power input positive Pin 2: power input negative Pin 3: Ground Pin 4: Unconnected Pin 5: output positive Pin 6: output negative Pin The functional layout of these pins is designed for its own specific reasons.
In practical applications, pins 1 and 2 are connected to the power supply, pins 3 are connected to the ground, and pins 5 and 6 are connected to the required load, so as to achieve the function of power output.
Pin 4 is not connected, which may be due to production or design needs to leave an interface for subsequent development and expansion.
It should be noted that for different chips and chips manufactured by manufacturers, the pin function may be different, and you need to carefully check the relevant data manual
