LPF-90 series
BLOCK DIAGRAM
fosc : 100KHz
90W Constant Voltage + Constant Current 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.
Should there be any compatibility issues, please contact MEAN WELL.
