Overview
RT7339P Active-PFC Constant-Voltage Controller with Primary-Side Regulation General 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 external component counts, the costs, and the volume of the driver board.
The RT7339P is compatible with the external depletion N-MOSFET to achieve fast startup and ultra-low standby pow...
