GR8818A
Features
- Description
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 pensation to pensate the voltage drop of the DC output cable to improve the load regulation. It minimizes the ponents 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 the abnormal conditions.
