Infineon Technologies REF_1KW_PSU_5G_GAN PSU with CoolGaN™
Infineon Technologies REF_1KW_PSU_5G_GAN PSU with CoolGaN™ Reference Board is developed to meet the demand for high efficiency in power supply units for modern applications. This is a complete system solution for a 1000W Power Supply Unit (PSU) targeting the new 5G specifications for outdoor small-cell telecom rectifiers and Edge computing. The REF_1KW_PSU_5G_GAN PSU comprises a front-end AC-DC bridgeless totem-pole PFC converter followed by a back-end DC-DC isolated Half-Bridge (HB) LLC converter. The front-end converter provides Power Factor Correction (PFC) and control of the Total Harmonic Distortion (THD). The LLC converter provides safety isolation and a tightly regulated output voltage at 12VDC. Typical applications include AC-DC power conversion for telecom infrastructure and server power supplies.
