PT2783 is a constant voltage, constant current primary side feedback control chip, built-in VCBO is 800V power transistor, suitable for chargers and adapters.

PT2783 adopts the unique output line loss compensation technology, which can effectively compensate the loss voltage drop of the output current on the output line.

PT2783 is the latest generation of constant voltage and constant current control chips, with dynamic response and driving performance, which can make greater output power.

PT2783 has multiple protection functions, including open circuit protection, overvoltage protection, short circuit protection functions, etc.
