L6566BH系列 23 V 4.6 mA SMPS 多模式 控制器 表面贴装 - SOIC-16N
Description
The L6566BH is an extremely versatile current-mode primary controller IC, specifically designed for high-performance offline flyback converters running off rectified 3-phase input lines. It is also suited to single-stage, single-switch, input-current-shaping converters single-stage PFC for applications that must comply with EN61000-3-2 or JEITA-MITI regulations.
Features
■ Selectable multimode operation: fixed frequency or quasi-resonant
■ On-board 840 V high voltage startup
■ Advanced light load management
■ Low quiescent current < 3 mA
■ Adaptive UVLO
■ Line feedforward for constant power capability vs. mains voltage
■ Pulse-by-pulse OCP, shutdown on overload latched or auto-restart
■ Transformer saturation detection
■ Programmable frequency modulation for EMI reduction
■ Latched or auto-restart OVP
■ Brownout protection
■ -600/+800 mA totem pole gate driver with active pull-down during UVLO
