产品概述 返回TOPDg1嘉泰姆

        CXAC85246 is a high performance Primary Side Regulation (PSR)controller with high precision CV/CC control ideal for charger applications. The IC can also support Quasi-Resonant (QR) Buck constant current topology for LED lighting if SEL pin is short to GND. In CV mode, CXAC85246adopts 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. CXAC85246 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), Gate Clamping, and VDD Clamping.
