In the constant voltage output mode, the cxac85195 adopts the multi-mode operation mode, that is, the combination of AM and FM, which improves the efficiency and reliability of the system

In the constant voltage output mode, the cxac85195 adopts the multi-mode operation mode, that is, the combination of AM and FM, which improves the efficiency and reliability of the system. In the constant current output mode, the chip adopts frequency modulation control mode and integrates constant current compensation of line voltage and load voltage. The chip works noiseless and ensures excellent dynamic performance. With the integrated line loss compensation function, high performance constant voltage output performance can be achieved. Cxac85195 has built-in complete protection functions: VDD undervoltage protection (UVLO), VDD overvoltage protection (OVP), cycle by cycle current limiting protection (OCP), short circuit protection (SLP), pin suspension protection, overheat protection and VDD clamping. Egcxac85195 is a high-performance, quasi resonant primary control power switch
