PFS5176F

HiperPFS ™ - 5 series advanced IC use 750 v power factor correctionPowiGaN™ switch low switching loss to improve efficiency.The high level of integration and innovation of control method helps to reduce size of components and the total inductance, so as to decrease the size of the system.The device adopts the ultra-thin InSOP - T28F encapsulation SMT type, can be directly to heat conduction on the PCB substrate heat sink without taking up space.Rugged HiperPFS - 5 devices at low input voltage to 305 vac within the scope of work, derating of more than 80%.

The product features

A highly integrated, compact appearance

• In general the input voltage applications can provide up to 240 w peak power output, and without heat sink
• Internal integration 750 v PowiGaN switch, can provide no loss current detection
• Can stay under 305 vac input voltage, high power factor and can work continuously during the input voltage soared to 460 vac
• Quasi resonant (QR) model of the DCM control can reduce switching loss, make the inductor size is smaller than the traditional CrM PFC, and allows the use of low-cost booster diode
• Internal integration X capacitor automatic discharge and recovering the high-voltage power supply function
• InSOP encapsulation back the source can be realized in the PCB cooling and reduce EMI effectively

In the whole load range high efficiency and high power factor

• Load from 10% to 100% load efficiency is as high as 98.3%
• In the 230 vac input under no-load power consumption < 40 mw
• 0.96 PF under 20% load
• Can be set by the power supply is ready (PG) signal can realize active control on surge

Users can choose the power limit can achieve rapid prototyping design: in the same test in the design of different types of HiperPFS - 5 IC, in order to realize rapid optimization

• Digital input voltage peak detection - even in uninterruptible power supply (UPS) or generator power supply when the voltage distortion situation still can provide reliable performance
• Enhanced digital power factor circuit to compensate for the distortion of EMI filters and rectifier bridge
• To achieve PFC stage in parallel in order to increase the output power
• Through IEC62368 safety certification
