The GL8258 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 minimizes the components counts and is available in a tiny SOT-26 package.
Key Features
Primary feedback control without secondary feedback signal Constant-Voltage(CV) and Constant-Current(CC) regulation Pulse by pulse Current Limiting Low start-up Current (6uA) Built-in soft start Wide VCC operation range VCC Over-Voltage Protection Output Over-Voltage Protection Cable Compensation for CV regulation SOT-26 package, with few external components needed.
High Power Factor & Accuracy Constant Current LED Driver
