IX9907N IXYS

IX9907 High Voltage, Dimmable LED Driver with PFC Control INTEGRATED CIRCUITS DIVISION Features Description Internal 650V, 2 power MOSFET The IX9907 is a quasi-resonant controller optimized Single stage, primary control with PFC and dimming for phase-cut dimmable, off-line LED applications. features Precise PWM generation supports phase-cut dimming >90% efficiency and power factor correction. Power factor >98% Wide operating voltage range The IX9907 incorporates an internal 650V power Digital soft-start MOSFET. It has a wide voltage operating range and Foldback correction and cycle-by-cycle peak current low power consumption. Multiple safety features control ensure full system protection under fault conditions. Output over-current and over-voltage protection With its strong feature set and low cost, the IX9907 is Over-temperature protection an excellent choice for quasi-resonant, off-line flyback Under-voltage lockout LED bulb designs. The IX9907 is available in a standard 8-pin SOIC Applications package.
