HB5810

PSR single stage active PFC LED driver IC Overview HB5810 HB5810 is a single-stage, high-precision with active power factor correction of primary-side LED current control IC for 85VAC-265VAC full range input voltage flyback LED power supply isolation. As a result of the critical continuous inductor current mode, power MOS at zero current state, the switching losses can be reduced, while increasing the efficiency of the transformer. Using a constant on-time mode of operation allows the simplification of peripheral circuits and high power factor correction. Chip provides multiple protection detection function can achieve high reliability LED lighting systems. Characteristics of a single-stage PFC converter to achieve> 0.90 power factor correction primary side feedback current control without secondary optocoupler feedback circuit, very low startup current (typically 12uA) 0.8A / 1.6A MOSFET driver capacity current critical continuous mode to achieve low switching losses short and open LED protection-by-cycle current limiting primary output overcurrent fast clamp COMP voltage chip power supply overvoltage and undervoltage protection over temperature protection automatic restart function ISEN electrical short-circuit detection gate drive voltage clamp 11V, lower switch loss of use TSOT23-6 package, minimalist peripheral applications. Application GU10 / E27 LED bulb lights, spotlights LED PAR30, PAR38 LED fluorescent lamp LED lighting Other
