AT6101Z
AT6101Z High-Efficiency CRM-CCM Multi-Mode Operation Power Factor Correction Controller
AT6101Z High-Efficiency CRM-CCM Multi-Mode Operation Power Factor Correction Controller
General Description
AT6101Z is a active power factor corrected controller to drive PFC boost stages base on ATK
patented Pseudo Digital Control(PDC) method.
In PDC loop,AT6101Z classically operates in Critical conduction Mode(CRM) when the inductor current
below a programmable value.
When the current is exceed this preset level,the AT6101Z natural change to Continuous conduction
Mode(CCM).The loop stab山ty and response is controlled by PDC Loop. AT6101Z features a robust suite
of protec tion features to properly handle an array of power supply operating and fault condition.
The devices is available in SOP-14L package and require few external devices for operation.
