目录产品概述 返回TOP 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.产品特点 返回TOP Multi-Mode PSR Control Audio Noise Free Operation for PSR Optimized Dynamic Response for PSR Low Standby Power<70mW ±4% CC and CV Regulation Programmable Cable Drop Compensation (CDC) in PSR CV Mode Built-in AC Line & Load CC Compensation Build in Protections: Short Load Protection (SLP) On-Chip Thermal Shutdown (OTP) Cycle-by-Cycle Current Limiting Leading Edge Blanking (LEB) Pin Floating Protection VDD UVLO, OVP & Clamp SOT23-6 package 应用范围 返回TOP Battery Chargers for Cellular Phones AC/DC Power Adapter 技术规格书（产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！
