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
