FAN9673
World’s First Three-Channel Interleaved CCM PFC Controller
FAN9673 is a compact and cost effective solution which is
designed for industrial AC/DC high power application. It enables
the power supply that fully complies with IEC1000-3-2
specification.
Key Features
•
Maximum Three Channels PFC Control, channel management
can be control by MCU or auto, good for efficiency
improvement at specific load
•
Programmable PFC Output Voltage to achieve best efficiency
•
RDY signal for communication to MCU for power saving &
sequence control
•
Differential Current Sensing to simplify application circuit with
the lowest cost, and gain higher efficiency
32-pin LQFP

FAN9673
World’s First Three-Channel Interleaved CCM PFC Controller
• Size Reduction
(61.6% in size reduction)
FAN9673 (2.5kW) : 30mm X 25mm X 29mm X 3
versus
Conventional CCM 1channel (2kW):66mm X 56mm X 46mm
• Compatible with common components
FAN9673 uses lower rating & common comp.
versus
Conventional CCM 1 channel requires higher rating comp.
1KW
5KW
• Replace Bucky Component
(via differential current-sense)
FAN9673 only requires a Resister/channel
versus
ICCM 2channel requires a Current transformer/channel
