A CRM PFC (Continuous Conduction Mode Power Factor Correction) Controller is an electronic device used in power supply circuits to improve power factor and overall energy efficiency. Power factor correction is important because it helps reduce the distortion of the AC current waveform and improves the utilization of electrical power, especially in applications with non-linear loads.

Description
The MAP8802 is an active power factor correction (PFC) controller for boost PFC applications that operates in critical conduction mode (CRM) In CRM operation, the on time is constant during the ac line cycle and the off time varies with the instantaneous input voltage.
The voltage mode CRM PFC controller does not need the input voltage sense line. It can reduce power loss. CRM operation is an ideal choice for medium power (100W~300W) PFC boost stages with the zero current switching of DCM operation […]
