采用SSL21082, TEA1721和JN5148的遥控非隔离11WLED驱动器参考设计

This application note provides basic information on the operation and performance of NXP Semiconductors SSL2108X_DR1166 reference design. It contains complete remote controller 11 W SSL Driver. However, the casing with heat sink, LEDs and 2.4 GHz antenna are not included in the shipment.

The design is based on buck topology which does not provide galvanic isolation. Using the RF remote control, brightness and on/off switch are controlled.
