The HiperPFS-4 family of power factor correction (PFC) ICs has been introduced by a leading company in the high-voltage integrated circuit industry, focusing on energy-efficient power conversion. Designed for applications requiring exceptional efficiency and power factor performance at both full and light loads, this new device is housed in a compact, electrically isolated, thermally efficient package. It integrates a 600V MOSFET for 305VAC input and features a high-efficiency variable frequency CCMPFC controller. The HiperPFS-4 not only delivers a high power factor of 0.95 and low THD but also maintains high efficiency across a wide output load range. This makes it ideal for meeting strict 80PLUS? Platinum and Titanium power standards.
Even at 20% of rated load, the HiperPFS-4 IC maintains a high power factor and low THD. It meets rigorous lightning requirements from major computer and entertainment equipment providers, including a 1-second 410VAC input test to ensure reliability against voltage surges and lightning strikes. The IC is suitable for hermetic designs up to 300W, open power supplies up to 400W, and high-voltage input applications up to 550W.
Key protection features include undervoltage lockout (UVLO), undervoltage (UV), overvoltage (OV), overtemperature (OTP), voltage ramp/drop protection, cycle-by-cycle current limit, and power limit protection. The HiperPFS-4 consumes less than 60mW at 230VAC and maintains output regulation at no load, with under 20mW in sleep mode.
Edward Ong, Product Marketing Manager at Power Integrations, emphasized that the HiperPFS-4 offers extremely high efficiency and power factor with low THD across a wide load range. The unique frequency sliding control technology allows for highly efficient operation at light loads, which is crucial for meeting EUCoC standards at 10% load. With an integrated 600V MOSFET and advanced protection features, the HiperPFS-4 is well-suited for regions with unstable input voltages. Its 305VAC input safety margin ensures safe PFC operation, making it ideal for data centers and commercial LED lighting. Additional applications include refrigerators, cordless tool chargers, and electric bike battery chargers.
Available in both high-voltage and low-voltage input configurations, the HiperPFS-4 is packaged in a thermally efficient eeSIP package, simplifying heat sink installation. Each unit is priced at $1.46 in quantities of 10,000. For more information, visit the official website.
