IN5L002-SAG (SOP-8)
High Power Factor Buck LED Driver Controller
General Description
The IN5L002 is a high power-factor, step-down converter with constant current driver IC for offline LED lamps. It can support wide input voltage range of 90V to 264VAC. It is based on a sinusoidal buck topology and achieves very high power factor, typically 0.95 or better.
The IN5L002 has a start-up current of less than 20uA. A bias winding on the buck converter’s inductor provides the VDD power to sustain circuit operation after start up.
The IN5L002 provides an adjustable pulse off-time for wide output power application. The IN5L002 provides an accurate internal average current reference voltage of 200mV.
The IN5L002 is available in SOP-8 package.
Feature
