产品概述 返回TOPuTv嘉泰姆

      CXAC85245A/B is a high performance Primary Side Regulation (PSR) power switch with high precision CV/CC control ideal for charger applications.  In CV mode, CXAC85245A/B adopts Multi Mode Control which uses the hybrid of AM (Amplitude Modulation) mode and (Frequency Modulation) FM mode to improve system efficiency and reliability. In CC mode, the IC uses PFM control with line and load CC compensation. The IC can achieve audio noise free operation and optimized dynamic response. The built-in Cable Drop Compensation (CDC) function can provide excellent CV performance.  CXAC85245A/B integrates functions and protections of Under Voltage Lockout (UVLO), VDD over Voltage Protection (VDD OVP), Cycle-by-cycle Current Limiting (OCP), Short Load Protection (SLP), and VDD Clamping.
