Power Integrations, Inc. PMIC - PMIC - PFC (Power Factor Correction) - PFS7329H PFS7329H

The PFS7329H from Lingto Electronic Limited is a high-power Power Factor Correction (PFC) controller designed for applications requiring efficient power management. It features an integrated high-voltage MOSFET and an ultra-low reverse recovery loss Qspeed diode, all within a compact eSIP package. This device supports a peak output power of up to 425 W and is optimized for high efficiency, achieving over 95% efficiency from 10% load to full load. The PFS7329H operates in continuous conduction mode (CCM) and employs a variable frequency control technique to minimize switching losses and reduce electromagnetic interference (EMI). It includes comprehensive protection features such as undervoltage (UV), overvoltage (OV), and thermal shutdown, which enhance reliability and reduce the need for external components. This PFC controller is compliant with EN61000-3-2 Class C and D standards, making it suitable for a variety of applications, including high-power adapters, industrial equipment, and LED lighting. The device's design simplifies thermal management and assembly, making it a practical choice for engineers looking to optimize their power supply designs.
