IN-PLUG® IPS101 Datasheet Rev.10 - High Efficiency Power Factor Correction Controller
IN-PLUG® series: IPS101
Low Cost, High Efficiency
Power Factor Correction Controller
INTRODUCTION
– REVISION 10 -
DESCRIPTION
The IN-PLUG® IPS101 is a special line-side
switching controller which provides simple yet high
performance active power factor correction. The
IPS101 was optimized for electronic ballast compact
SMPSs up to 300W that requires a minimum board
area, reduced component count and high efficiency.
The PFC forces the SMPS to draw a current
proportional to the instant AC line voltage in order to
charge a storage capacitor thus resulting in excellent
power factor and low line harmonics generation.
The output of the PFC is a regulated voltage which
slightly exceeds the peak line voltage and is generally
too high to be used as is. This is why a PFC is usually
followed by a DC/DC converter, providing one or
more isolated output(s) at the required voltage(s).
AAI offers the following solutions for the DC/DC
converter:
Flyback converters (see IPS10 series)
Push-pull converters (see IPS201 controller)
Other ICs and discrete solutions can be used as well.
More and more countries already impose PFC above
75W or soon will enforce this obligation.
In addition to the compliance with power factor and
line harmonics regulations, using a PFC offers other
advantages like:
Reducing the utility bill by making the actual
power drawn from the line almost equal to the
apparent power paid to the utility company
Allowing to draw more power from the wall
outlet or line circuit breaker without exceeding
the limits set by UL or other safety agencies.
FEATURES
Simple and easy to use.
High efficiency over 96% (in optimized designs)
Minimum external component count for lowest
cost.
3-input current-mode multiplier ensures
outstanding performance at any line voltage and
any load.
