Overview
L6585DE Combo IC for PFC and ballast control Features ■ PFC section – transition mode PFC with over-current protection – over-voltage protection – feedback disconnection – under-voltage lockout – PFC choke saturation detection – THD optimizer Half-bridge section – preheating and ignition phases independently programmable – 3 % oscillator precision – 1.
2 µs dead time Block diagram SO-20 – programmable and precise end-of-life protection compliant with all ballast configurations – smart hard switching detection – fast ignition voltage control with choke saturation detection – half-bridge over-current control ■ Figure 1.
