BP1808 PDF – Buck and Buck-Boost DC/DC LED Driver

Part Number: BP1808

Function: Buck and Buck-Boost DC/DC LED Driver

Package: SOP 8 Pin Type

Manufacturer: BPS


BP1808 pinout datasheet



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 Buck-Boost 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.

BP1808 offers rich protection functions including VDD under voltage protection, output over voltage protection, cycle-by-cycle peak current limit and thermal regulation.
