Transition mode PFC controller for flyback converters
Datasheet -Production data converters operated in transition mode (aka
quasi-resonant operation). Targeting both indoor
and outdoor solid-state lighting applications, it
provides extended temperature range operation
down to -40 °C with guaranteed electrical
specification.
The main feature of this IC is a special circuit
(Input Current Shaper, ICS), that enables High-PF
quasi-resonant flyback converters to draw a
theoretically sinusoidal input current from the
power line, unlike the traditional control. Features
 Transition-mode (quasi-resonant) control of
flyback PFC pre-regulators
 Proprietary input current shaper for minimum
THD of line current
 Control input for isolated feedback and
optocoupler driving
 Output overvoltage protection
 Overload and short-circuit protection
 Low (≤ 60 μA) start-up current and low (≤ 4 ma)
quiescent current …
