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 protection, under-voltage protection, open
feedback loop protection, overcurrent protection, PFC
output/bypass diode short protection, ZCD winding short
protection.
MAP8802 is a available in an SOP-8 Pin package. The
device operates over the -40°C ~ 125°C temperature.
