MBI6902 regulates the output current within ±5% of the preset current by well controlling the external MOSFET. In addition, LED dimming control can be implemented by connecting the output of a photocoupler to the DIM pin. MBI6902 is also characteristic of protecting the controller from fault conditions, inclusive of under voltage lock-out (UVLO) and over voltage protection (OVP). To ensure system reliability, thermal protection (TP) is built-in to prevent IC from over temperature (155°C) by turning off the external MOSFET. Once the temperature drops below 125°C, the external MOSFET will resume working.
