AT6105Z High-Efficiency CRM/CCM Multi-Mode Operation Power Factor Correction Controller
General Description
AT6105Z is an active power factor corrected controller to drive PFC boost stages base on ATK patented Pseudo Digital Control (PDC) method.
In PDC loop, AT6105Z could operates in traditional fixed frequency operation for Continuous Conduction
Mode (CCM) in heavy loading and Discontinuous Conduction Mode (DCM) in lighter loading.
By optionally utilizing ZCD pin to sensing demagnetization of inductance, AT6105Z could also operates in Critical Conduction Mode (CRM).
The loop stability and response of these multi-mode operations is well controlled by PDC Loop. AT6105Z
features a robust suite of protection features to properly handle an array of power supply operating and fault
condition.
The devices is available in SOP-14L package and requires few external devices for operation.
