PT2206
Primary Side Constant Voltage Regulator
GENERAL DESCRIPTION
The PT2206 is a high performance AC/DC power
supply regulator which integrates a 730V power
switch.The PT2206 operates in quasi-resonant mode at
heavy load to provide high efficiency along with a
number of key built-in protection features while
minimizing the external component count, and lowering
the total bill of material cost. The PT2206 removes the
need for secondary feedback circuitry while achieving
excellent line and load regulation. It also eliminates the
need for loop compensation components while
maintaining stability at all operating conditions. The
device uses PFM technology to enableoptimized
transformer design in off-line applications over a wide
input voltage range. Excellent EMI performance is
achieved with frequency jittering function.
The ultra-low operating current at light load ensures
that the PT2206 is ideal for applications targeting the
newest regulatory standards for average efficiency and
standby power.
The PT2206 is available in an SOP-8 and DIP8 package
