HV9906DB3 Off-Line PFC Current Source Controller

HV9906DB3 Off-Line PFC Current Source Controller Introduction The Supertex HV9906DB3 demo board is a power factor corrected (PFC) LED driver using the HV9906 IC. A power converter of the demo board consists of an input buck-boost stage and an output buck stage. The output voltage polarity is negative. Due to its unique quadratic input-to-output DC voltage transfer ratio, the converter can operate directly off AC line to produce low-voltage output without need for electrolytic capacitors. The HV.

HV9906DB3 Features

* passive power factor correction to PF>0.95. The board is optimized for driving a 500mA (700mA max.) LED array. (Forced cooling or encapsulation is required to achieve an output current higher than 500mA.) Features

* Off-Line Transformerless Power Conversion P
