Power Integrations introduces the HiperPFS-4 power factor correction IC to achieve an efficiency of 98 for PFC designs up to 550 W
The leader in the high-voltage integrated circuit industry dedicated to energy-efficient power conversion today introduced the HiperPFSTM-4 family of power factor correction (PFC) ICs. The new device family is suitable for applications that require excellent efficiency and power factor performance at full load and light load. The HiperPFS-4 device is housed in a compact, electrically isolated, thermally dissipative package that integrates a 600V MOSFET for 305VAC input and a high efficiency variable frequency CCMPFC controller. Not only does the IC family offer high power factor and low THD, but it also delivers high efficiency over a wide output load range, enabling OEMs to meet stringent 80PLUS? Platinum and Titanium power standards. The HiperPFS-4 IC achieves a high power factor of 0.95 and low THD even at 20% rated load. The new device also meets the stringent lightning requirements of major computer and entertainment equipment providers, such as the 1-second 410VAC input test, which is designed to ensure reliable reliability and withstand voltage surges and lightning strikes. Sex. The new HiperPFS-4 IC is suitable for hermetic design up to 300W, open power supply up to 400W and high voltage input applications up to 550W. Specific protection features include undervoltage lockout (UVLO) protection, undervoltage (UV) protection, overvoltage (OV) protection, overtemperature protection (OTP), voltage ramp/drop protection, cycle-by-cycle current limit, and power limit protection. The HiperPFS-4IC consumes less than 60mW at 230VAC and maintains output regulation at no load, with less than 20mW in sleep mode. Edward Ong, Product Marketing Manager at PowerIntegrations, said: "The HiperPFS-4 product family offers extremely high efficiency and power factor and low THD over a very wide load range. The HiperPFS-4 uses a unique frequency sliding control technology that allows the power supply to be designed Extremely efficient at light loads, this advantage is important for the EUCoC standard that meets the efficiency requirements of 10% load. The IC family integrates a 600V power MOSFET with many advanced protection features, so it is very Suitable for countries with severe input voltage fluctuations. HiperPFS-4 devices have a good 305VAC input safety margin to ensure safe operation of PFC, especially suitable for data center and commercial LED lighting. Other applications include refrigerators (will contain high PFC Performance requirements), cordless tool chargers and electric bike battery chargers." The HiperPFS-4IC is available in high-voltage input and low-voltage input applications, respectively, and is packaged in an extremely thermally dissipative eeSIP package to simplify heat sink installation. The unit is priced at $1.46 each in 10,000-piece quantities. Please visit the relevant website:
