Product Description
MBI6911 is a 85~135V input AC-DC converter designed to deliver constant current with thermal fold-back Feature. The built-in active power factor correction circuit maintains high power factor over a wide input voltage range. MBI6911 is optimized for interior power applications, and the efficiency is enhanced with quasi-resonant switching technique. MBI6911 is also featured with under voltage lock-out (UVLO), over temperature protection (OTP), over-voltage protection and LED short-circuit protection to protect the converter from being damaged accidentally. A thermal resistor can be used with an external voltage divider circuit to adjust the output current level automatically. If this feature is used to monitor an output current related heat source, a temperature balance condition should be expected.
