MAP8802 – Critical Conduction Mode PFC Controller Datasheet Version 1.
3 MAP8802 CRM PFC Controller General Description Features 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.
MAP8802 provides protection functions such as overvoltage prote...
