MBI6912

Macroblock Preliminary Datasheet MBI6912 High Power Factor AC/DC LED Driver Features  Constant current LED driver  Voltage step down design  Built-in active power factor correction  Quasi-resonant switching  Universal input voltage range  Full protection: Thermal shutdown VDD over voltage (OVP) Under voltage lock-out (UVLO) LED open-/short- circuit Current sensing resistor open/short-circuit Compensating capacitor open/short-circuit  Available in SOT-236 package  Package MSL Level : 3 Product Description MBI6912 is a universal input AC-DC converter designed to deliver constant current with step down control. The built-in active power factor correction circuit maintains high power factor over a wide input voltage range. MBI6912 is optimized for applications of output power up to 50 Watt, and the efficiency is enhanced with quasi-resonant switching technique. MBI6912 is also featured with under voltage lock-out (UVLO), over temperature protection (OTP), LED open-circuit protection and LED short-circuit protection to protect the converter from being damaged accidentally. MBI6912 is specifically designed with current sensing resistor short protection to prevent MOSFET over-current caused by manufacturing defect such as solder splash or abnormal operation such as accidental short-circuit by earthquake. Applications  T8 light tube LED alternative solutions  E26/E27 light bulb LED alternative solutions  PAR light LED alternative solutions  Interior LED power module...
