Einführung
Introduction of FAN9612 - Interleaved Dual BCM PFC Controller
Efficiency
• Interleaved Æ Lower Turn-off Losses
• Valley Switching Æ Minimize COSS losses
• Strong gate drivers Æ reduce switching losses • Boost-follower (“tracking boost”) possible
Protection
• Closed-loop soft-start w/ Prog. Ramp Time
• Power and Current Limit per Channel
• Input Voltage Feed-forward • Secondary Latched OVP
• Input Brown-out Protection
• Line OVP
• Internal maximum fSW clamp limit
Ease of Design & Solution Size
• Easy Valley Detection Implementation
• Easy Loop Compensation (constant BW and PWM Gain)
• Integrated +1.8A/-1.0A Gate Drivers
• Works with DC, 50Hz to 400Hz AC Inputs
