BP1808A - Buck and Buck-Boost DC/DC LED Driver

Datasheet Summary

Features

  • The BP1808A is a DC/DC constant current LED driver.
  • Wide 3V to 70V Input Voltage Range with an integrated 80V/300mΩ MOSFET designed for.
  • Supporting Boost Buck-Boost Buck a wide input-voltage range of 3V to 70V. The BP1808A Topology can be configured as Buck, Boost and Buck-Boost topology. l With a current sense reference of 200mV, the LED current is programmed by an external current sense tia resistor and the power loss is minimized. The BP1808A allows both analog and PWM dimmin.
