27 Product Description MBI6904 is a high efficiency buck-boost AC/DC controller designed to deliver constant output current.
The input voltage range of MBI6904 application is universal from 85VAC to 265VAC.
It is featured by a PWM control scheme.
MBI6904 is designed to operate with active power factor correction (PFC) circuit and is therefore capable of maintaining system power factor greater than 0.
9 with proper design.
MBI6904 regulates the output current within ±5% of th...
