AT6101L High-Efficiency CRM / CCM Multi-Mode Operation Power Factor Correction Controller
General Description
AT6101L is a active power factor corrected controlIer to drive PFC boost stages base on ATK
patented Pseudo Digital Control(PDC) method.
In PDC loop,AT6101L classically operates in Critical conduction Mode(CRM) when the inductor current
below a programmable value.
When the current is exceed this preset level,the AT6101L natural chage to Continuous conduction
Mode(CCM).The loop stab山ty and response is controlled by
PDC Loop. AT6101L features a robust suite of protec tion features to properly handel an arry of
power supply operating and fault condition.
The devices is available in SOP-14L package and require few external devices for operation.
