RT7339P Description
The RT7339P is a constant voltage controller with the active Power Factor Correction (PFC), which is designed to meet the line current harmonic regulations. It drives the converter in Quasi-Resonant (QR) mode to achieve higher efficiency. By using the Primary-Side Regulation (PSR), the RT7339P controls the output voltage accurately without a shunt regulator and an opto-coupler at the secondary side, reducing the...
