L6564DTR 电源管理芯片

L6564DTR

功率因数校正 - PFC Transition Mode PFC 5mA 90uA 1.5% Ref 10-pin controller

Description  

The L6564DTR L6564 device is a current mode PFC controller operating in transition mode (TM) and  represents the compact version of the L6563S device as it embeds the same driver,  reference and control stages in a very compact 10-pin SSOP10 package.

The highly linear multiplier, along with a special correction circuit that reduces crossover  distortion of the mains current, allows wide range mains operation with an extremely low  THD even over a large load range.

Applications L6564DTR

 PFC preregulators for:

– High-end AC-DC adapter/charger
