MBI6665 is a Buck、Boost and Buck-Boost topology constant-current high-brightness LED driver to provide a reliable design solution for particular power automotive illumination applications.
The output current of MBI6665 can be programmed by an external resistor and dimmed via either pulse width
modulation (PWM) or voltage altering.
While the power is switched on. Thermal shutdown guards the system to be robust and keep the driver away from
being damaged which results from LED open-circuited, and other abnormal events. With an error report pin, short
circuit conditions can be reported to a possible external mechanism for further control decision making. MBI6665 is
packaged in the thermal-enhanced TSSOP20 or QFN20 for efficient power dissipation.
