半數位功率因數IC

General Description
AT6108Z is an active power factor corrected controller to drive PFC boost stages base on ATK
patented Pseudo Digital Control (PDC) method.
In PDC loop, AT6108Z could operates in traditional fixed frequency operation for Continuous Conduction
Mode (CCM) in heavy loading and Discontinuous Conduction Mode (DCM) in lighter loading.
The loop stability and response of operations is well controlled by PDC Loop. AT6108Z features a robust
suite of protection features to properly handle an array of power supply operating and fault condition.
The devices is available in PSOP-8L package and requires few external devices for operation.

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.

General Description
AT6102Z is a active power factor corrected controller to drive PFC boost stages base on ATK patented Pseudo Digital Control(PDC) method.
In PDC loop ,AT6102Z classically operates in Critical conduction Mode(CRM) when the inductor current below a programmable value.
When the current is exceed this preset level ,the AT6102Z natural change to Continuous conduction
Mode(CCM).The loop stability and response is controlled by PDC Loop. AT6102Z 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-10L package and require few external devices for operation.

General Description
AT6101L is a active power factor corrected controlIer to drive PFC boost stages base on ATK
