ML4841 Datasheet - Fairchild

ML4841 Variable Feedforward PFC/PWM Controller Combo

The ML4841 is a controller for power factor corrected, switched mode power supplies. Power Factor Correction (PFC) allows the use of smaller, lower cost bulk capacitors, reduces power line loading and stress on the switching FETs, and results in a power supply that fully complies with IEC1000-2-3 sp.

ML4841 Features

* Internally synchronized PFC and PWM in one IC

* Low total harmonic distortion

* Reduces ripple current in the storage capacitor between the PFC and PWM sections

* Average current, continuous mode, boost type, leading edge PFC

* High efﬁciency trailing edge P
