Navitas wins Samsung Galaxy design


Galaxy S23 phone 25W fast charger design to use next-gen GaNFast technology

Navitas Semiconductor has announced a GaNFast win at Samsung, this time a new 25W charger for the Galaxy S23 smartphone.

The Galaxy S23 features a Dynamic AMOLED 2X, 120Hz screen with 1750 nits peak contrast, stretching it’s 1080 x 2340 pixels across 90.1 cm2 of Corning Gorilla Glass. With a Qualcomm Snapdragon 8 Gen 2 chip, up to 512GB / 8GB RAM of storage and triple cameras up to 50 MP, the S23 excels in mobile communication performance.

For power, the S23 features a 3900 mAh Li-Ion battery, and with the GaNFast 25W charger (model EP-T2510) with USB PD 3.0 interface, reaches 50 percent charge in only 30 minutes, and while in sleep mode, consumes only 5 mW of power. The PD 3.0 specification means that the new charger can power a range of devices from Galaxy Buds2 audio to Galaxy Z Fold5, Galaxy Flip and Galaxy A23.

Navitas’ GaNFast technology is used in a high-frequency, quasi-resonant (HFQR) topology running at 150 kHz. In this way, it shrinks the charger by more than 30 percent, according to the company.

“As pioneers in mobile fast charging, Navitas continues to lead the next-gen market, with all ten of the top ten mobile OEMs in production with GaNFast products,” said David Carroll, SVP Worldwide Sales.
