PT6923DB2V1.0
3-Segment AC Input HV LED Driver
-Special Designed For 6W LED Light Bulb-
General Description
PT6923 is a special current
regulator to drive HV LED with 3-Segment driving topology which will improve power factor, THDI and efficiency. EMI issue will be avoided by special technology during segment switching. Few external components, no capacitor and temperature compensation design which makes low price & long life LED bulbs possible.
