This reference design is a gallium nitride (GaN) based, 140W AC-DC power with high efficiency and power density. The design supports wide input (90V–264VAC) and output (5V–28V) voltage. The Power Factor Correction (PFC) is designed with UCC28056 which is a Transient Mode (TM) boost PFC controller plus LMG3622 device which is a 650V, 120mΩ GaN device with integrated driver. The DC-DC stage was designed by Asymmetric Half-Bridge Flyback (AHB) plus LMG2610 which is a 650V asymmetric half-bridge GaN (170mΩ–248mΩ) device with high- and low-side driver, level shift, and bootstrap diode integrated in 7mm × 9mm QFN package to minimize the PCB space. This reference design is customized for the application, such as the adapter design for USB power delivery (PD) 3.1 and the charger for power tools.
