我司代理闽台安葳科技的AP1910,可**替代HV9910,SMD802等,是用于T8日光灯,球泡灯上理想的驱动方案。 General Description The AP1910D is a high-efficiency LED driver control IC. It drives LEDs with constant current and uses fewer components. The AP1910D is an open loop, current mode control IC. It can be programmed to operate in either a constant frequency or constant off-time mode. It includes an 12~500V linear regulator which allows it to work in wide input voltage range without external low voltage power supply. The AP1910D is recommended in buck LED drivers applications, LED luminance can be easily adjusted by AP1910D's 0~** PWM dimming and 0~245mV linear dimming functions The AP1910D is suitable for buck LED drivers. The system has excellent stable response because of open loop current mode control. The controller achieves good output current regulation and need no compensation Features ? Buck system efficiency:>90% ? Open loop peak current controller ? Internal 12~500V linear regulator ? Constant Current LED Driver ? Support linear and PWM dimming interface ? Requires few external components ? 8 Lead SOP Packages ? RoHS Compliant and ** Lead (Pb)-Free and Green (Halogen Free with Commercial Standard) ? Constant off time function for over 50% duty cycle applications ? AP1910D_V0.3.pdf (427.67 KB, 下载次数: 2)
