PT2206 - Primary Side Constant Voltage Regulator

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

• 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.
