BP1808A
Overview
- 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 dimming by DIM pin.
- The fixed 420kHz operating frequency minimizes size of external inductor, input and output capacitor. e Current mode operation provides fast transient response and easy loop stability. fid BP1808A offers rich protection functions including VDD under voltage protection, output over voltage protection, cycle-by-cycle peak current limit and n thermal regulation. o The BP1808A adopts SOP8-EP package for enhanced C power dissipation.
