Cxac85205 The chip can work without noise and optimize dynamic response. With the integrated line loss compensation function, high performance constant voltage output performance can be achieved

Cxac85205 has a variety of protection functions: VDD undervoltage protection (UVLO), VDD overvoltage protection (OVP), cycle by cycle current limiting protection (OCP), short circuit protection (SLP), gate clamp and VDD clamp. Cxac85205 is a high-performance primary side controller, and its high-precision constant voltage and constant current control can be used in charger products. When sel is grounded, the chip can also be used as a quasi resonant constant current topology in LED lighting.
   in constant voltage mode, the cxac85205 adopts multi-mode control, which uses AM FM mixing to improve the efficiency and reliability of the system.
