Product Description
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.
Applications
z T-8 CFL Replacement LED Solution
z E26/E27 Light Bulb Alternative LED Solution
z General Illuminations
z Power Supply for Light Panel
