Isolated Flyback Controller with PFC Controls Voltage or Current

March 01, 2012 // By Electronics EETimes

Linear Technology's LT®3798 isolated controller with active power factor correction (PFC) is specifically designed for regulating bus voltages or driving constant current applications over a wide input range of 10V to 480V. The unique current sensing scheme delivers a well regulated voltage or current to the secondary side with no optocoupler. Output short circuit protection ensures long term reliability and a simple, compact solution footprint addresses a wide range of applications.
