The SOP – 7 encapsulation
Ac4n power supply chip Ac4n
1 Power supply pin for VDD chip.
2-3 FB system feedback pin. The voltage of the auxiliary winding is sent to the FB pin after the resistance voltage divider, which is used for CV mode output voltage control and CC mode output current control.
4 CS current sampling input pin.
5-6 C Built-in power transistor collector.
7 GND Chip reference ground.
Acn 13 switch power chip can also easily replace many brands of acn. Out of stock market survival of the fittest, timely adjustment of the program, can enter the mass production stage as soon as possible.
