The LYT6079C-H125 from Power Integrations is a Flyback CV/CC LED Driver IC that is ideal for isolated off-line LED drive, high-voltage flyback post regulator, and smart LED lighting applications. It requires an input voltage of 85-305 V. This driver delivers an output power of up to 100 W and has an efficiency of less than 94%. It can dramatically simplify the development and manufacturing of off-line LED drivers, particularly those in compact enclosures or with high efficiency requirements. The architecture of this driver includes a high-voltage switch, primary/secondary controllers with sense elements, and a FluxLink feedback mechanism. This feedback mechanism is a communication link located near the components, permitting accurate control of a secondary-side MOSFET with quasi-resonant switching of a primary-side switch to achieve high efficiency.
This LED driver is equipped with over-voltage protection, under-voltage protection, FET open gate detection, and input voltage monitoring to prevent damage to the input and output ports. It also supports thermal foldback functionality to ensure that power continues to be delivered at elevated temperatures. This RoHS-compliant driver IC’s design contributes to low heat dissipation and easily meets Energy Star rating, along with all other global lighting energy efficiency regulations. It is available in a surface-mount package that measures 13.43 x 9.40 mm.
