Overview

® RT7300 Active PFC Controller with Critical Conduction Mode General Description The RT7300 is an active Power Factor Correction (PFC) controller with critical conduction mode (CRM) operation that is designed to meet line current harmonic regulations for the applications of AC/DC adapters, electronic ballasts and medium off-line power converters (<300W).
The CRM and Feed-Forward schemes provide near unity power factor across a wide range of input voltages and output powers.
The totem-pole gate driver with 600mA sourcing current and 800mA sinking current provides powerful driving capability for P-MOSFET to improve conversion efficiency.
The RT7300 features an extra low start-up current (≤20μ...
