AT6108Z

AT6108Z High-Efficiency DCM/CCM Multi-Mode Operation Power Factor Correction Controller

AT6108Z High-Efficiency DCM/CCM Multi-Mode Operation Power Factor Correction Controller

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.
