The product description
9101HT is a high power factor linear constant current driver on high voltage LED chips, used in LED lighting field.The IC 9101HT through a unique patented technology, constant current control to realize constant current precision is less than ±5%, the output current can be regulated by the external R1 resistance. The IC 9101HT with high power factor and low harmonic distortion.
9101HT have the function of the output current with the temperature automatic adjustment. When the temperature is too high, it will reduce the output current, in order to achieve the effect of lowering the temperature, temperature protection point can set through the pin RTH’s external resistance.
9101HT has the function of the input power automatic adjustment when the input voltage is too high, it will reduce the output current, reduce the magnitude of the current through the external resistors RD Settings, to ensure the input power does not change with the input voltage
Simple system structure , the IC 9101HT has a variety of protection function without transformer and electrolytic capacitor, the IC 9101HT use few peripheral components, can save the space of electronic components, which can realize all SMT processing and full automatic operation.
