SSL2109AT Overview
Description
The SSL2109AT is a high-voltage Integrated Circuit (IC) for driving LED lamps in general lighting applications. The main benefits of this IC include: - Small Printed-Circuit Board (PCB) footprint and compact solution - High efficiency (up to 95 %) for non-dimmable high power factor solutions - High power factor >0.9 (application dependent) - Ease of integration and many protection features - Low electronic Bill Of Material (BOM) - Highly flexible IC for use in buck, buck/boost and flyback modes - Single inductor used for non-isolated configurations because of internal demagnetization detection and dV/dt supply The IC is supplementary to the SSL21081/SSL21083 series but without an internal switch.
Key Features
- LED driver IC for driving strings of LEDs or high-voltage LED modules from a rectified mains supply
- Part of a high-efficiency switch mode flyback or buck product family. Driver-only which can drive an external MOSFET
- Suitable for high power factor (>0.9) applications
