HA220XXPB High Voltage LED Constant Source IC General Description Constant current source IC is a kind of power supply converter with a constant current output. This constant current source IC is mainly applied to supply power of LEDS in series. When the input voltage is 220VAC, with red LED, the number of LEDs in series can up to 110. The input voltage is 85-240VAC,output a constant current that the value can be preset by peripheral resistance. The peripheral circuits is concise, the whole circ
