The chip control engine also has the power factor enhancement function (PFE), that is, in the case of high voltage input light load, the control engine will fine-tune the input current waveform to compensate the influence of the input EMI filtering capacitor and the decoupling capacitor at both ends of the circuit bus on the power factor and harmonic current. This ensures that the power factor will be higher than 0.96 even under light load.

Mr Edward Ong, senior product marketing manager at PI, said: "In the context of OEM OEM and non-OEM suppliers racing to come up with the fastest, smallest and most versatile USB PD charger for mobile devices, the HiPERPDS-5 IC can provide key advantages to engineers. We can combine the PowiGaN switch unique to PI with the PFC topology of quasi-resonant, frequency conversion discontinuous conduction mode boost. "When paired with our new HiperPFS-5 chipset or InnoSwitch4-CZ Active Clamp flyback IC, design engineers can easily exceed even the most stringent efficiency standards while cutting the bill of material in half to create a compact, ultra-fast charger."
