Power Integrations, Inc. PFC (Power Factor Correction) PFS7535H

The PFS7535H is a Power Factor Correction (PFC) controller from the HiperPFS-3 family, designed for high efficiency and power factor across a wide load range. It features an integrated high-voltage MOSFET and a Qspeed diode, achieving over 95% efficiency from 10% load to full load and a power factor greater than 0.92 at 20% load. The device operates in continuous conduction mode (CCM) and utilizes a variable frequency control technique to optimize performance and minimize electromagnetic interference (EMI). This PFC controller supports peak output power of up to 480 W in high-line applications and is suitable for various applications, including PCs, high-power adapters, industrial equipment, and LED lighting. It includes comprehensive protection features such as undervoltage lockout (UVLO), overvoltage (OV), and thermal shutdown, which enhance reliability and reduce the need for external components. The PFS7535H is packaged in an eSIP-16D format, facilitating easy integration into designs while minimizing board space and assembly costs.
