FM8101D
product description
FM8101 is a high-precision isolated flyback LED constant current control chip. The chip works in inductive current discontinuous mode and is suitable for isolated flyback LED lighting applications in the full voltage range of 85VAC-265VAC.
The FM8101 chip integrates a 650V power switch, adopts high-precision sampling, compensation circuit and high-voltage JFET power supply technology, without starting resistance and VCC capacitor, without auxiliary winding power supply and detection, to achieve high-precision LED constant current output and excellent line voltage The adjustment rate, coupled with accurate and stable adaptive technology, makes the system periphery very simple, and can achieve high-precision constant current control under the condition of a very small number of peripheral components, which greatly saves the system cost and volume, and can ensure that the system can be used in batches. Consistency of LED power parameters during production.
FM8101 has multiple protection functions, including LED short circuit protection, open circuit protection, chip temperature overheating adjustment functions, etc.
