The GR8818A is an excellent primary side feedback controller.
It’s integrated constant voltage (CV) and constant current (CC) regulation functions.
While it operates on CV mode, it’s built-in the cable compensation to compensate the voltage drop of the DC output cable to improve the load regulation.

he GR8818A is an excellent primary side feedback controller. It’s integrated constant voltage (CV) and constant current (CC) regulation functions. While it operates on CV mode, it’s built-in the cable compensation to compensate the voltage drop of the DC output cable to improve the load regulation. It minimizes the components counts and is available in a tiny SOT-26 package. Those make it an ideal design for low cost applications. It provides functions of low startup current, greenmode power-saving operation,. Also, the GR8818A is built-in the VCC over-voltage protection and FB pin to prevent the circuit being damaged from
