Power Integrations INN4077C-H182 | Demoboard DER-957

Description

This engineering report describes a high power density 130 W USB PD 3.1 external power supply that can provide 5 V / 3 A, 9 V / 3 A, 15 V / 3 A, 20 V / 5 A and 28 V / 4.65 A outputs. This was made possible using three innovative PowiGaN-Based devices InnoSwitch4-CZ INN4077C, ClampZero CPZ1076M, and HiperPFS-5 PFS5177F. The PSU contains a highly-efficient boost Power Factor Corrector (PFC) and flyback DC-DC converter.This design demonstrates high power density and efficiency that is made possible due to the high level of integration of the InnoSwitch4-CZ active clamp controller providing exceptional performance and is paired with high efficiency power factor correction (PFC) IC PFS5177F.The report contains the power supply specification, schematic diagram, printed circuit board layout, bill of materials, magnetics and adapter case specifications, and performance data.
