BLOCK DIAGRAM

50W linear LED Driver

※ This series is able to work in either Constant Current mode (a direct drive way) or

Constant Voltage mode (usually through additional DC/DC driver) to drive the LEDs.

DRIVING METHODS OF LED MODULE

Typical output current normalized by rated current (%)

In the constant current region, the highest voltage at the output of the driver

depends on the configuration of the end systems.
