Macroblock MBI6804
MBI6804 is a universal input AC-DC converter designed to deliver constant current with primary side regulation (PSR) control. The built-in active power factor correction circuit maintains high power factor over a wide input voltage range. MBI6804 is optimized for applications of output power up to 50 Watt, and the efficiency is enhanced with quasi-resonant switching technique.| Part No. | MBI6804 |

DESCRIPTION
MBI6804 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. MBI6804 is specifically designed with current sensing resistor short protection to prevent MOSFET over-current and transformer saturation caused by manufacturing defect such as solder splash or abnormal operation such as accidental short-circuit by earthquake.
