RS2330 - THD Optimized CRM PFC Controller - PTC 数据手册 ( 数据表 )

DESCRIPTION
RS2330 is an active transition-mode (TM) power-factor-correction (PFC) controller for AC/DC switching mode power supply applications.
RS2330 features an internal start-up time for stand-alone applications, a quadrant multiplier with THD optimizer for near unity power factor, zero current detector (ZCD) to ensure TM operation, a current sensing comparator with built-in leading-edge blanking, and a totem pole output ideally suited for driving a power MOSFET.

FEATURES
• Active transition-mode(TM) optimizer
• One quadrant multiplier with THD optimizer
• Low dynamic OVP sensing current setting
• Low start-up current and operating current
• Cycle-by-cycle current limiting
• Internal RC filter
• Trimmed 1.5% internal band-gap reference
• Under Voltage Lockout (UVLO) with hysteretic
   static output Over-Voltage Protection(OVP)
• Internal start-up timer for stand-alone clamping
• Disable function
• Totem pole output with high state clamping
• Proprietary audio noise free operation
• 11V to 32V wide range of VCC voltage
• 3000V HBM ESD
• SOP-8L green package

APPLICATIONS
• Single stage high PF flyback AC/DC SMPS
• LED lighting power
