Step-Down 1A Dimmable LED Driver MBI6653

 Step-Down 1A Dimmable LED Driver

Задание
MBI6653 is a step-down constant-current high-brightness LED driver to provide a cost-effective design solution for interior/exterior illumination applications. It is designed to deliver constant current to light up high power LED with only 4 external components. With hysteretic PFM control scheme, MBI6653 eliminates external compensation design and makes the design simple.

    MBI6902 is a high efficiency step-down AC/DC controller designed to deliver constant current. The input voltage range of MBI6902 is universal from 80VAC to 265VAC. It is featured by a hysteretic PFM control scheme which enhances the efficiency in light load conditions. 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. MBI6902 is available in MSOP-8L package.
