Description
- HV9861ADB2, Demo Board for the HV9861A LED driver, boost assisted, valley fill, 120VAC input, 7W output, 350mA, 20V, 93% power factor. Certain target markets for LED lighting require a power factor of at least 90%. A power factor over 90% can be attained using valley fill power factor correction with the addition of a small boost converter. The boost converter lowers line current distortion by adding line current draw in the valley and lowering the peak amplitude of the valley fill capacitor recharging current
