BP1808 Description
The BP1808 is a DC/DC constant current LED driver with an integrated 70V/300mΩ MOSFET designed for a wide input-voltage range of 3V to 60V. The BP1808 can be configured as Buck, Boost and BuckBoost topology. With a current sense reference of 200mV, the LED current is programmed by an external current sense resistor and the power loss is minimized.
