Driving Performance In GaN-Based USB-C Adapters And Chargers With EPR


With the announcement of the USB PD 3.1 standard [1], higher power levels of up to 240 W are enabled. Still, the wide output voltage range from 5 V to 48 V raises new challenges for the converter topologies currently in use. In this white paper, the combination of an AC-DC PFC boost and a DC-DC hybrid flyback (HFB) stage [2], also well known as asymmetrical half-bridge flyback topology, is prop... » read more

Week In Review: Auto, Security, Pervasive Computing


Pervasive computing — data center, edge, IoT Maxim Integrated’s new USB-C Power Delivery products — the MAX77958 USB-C PD controller and the MAX77962 28W buck-boost charger — are aimed at devices, such as IoT or mobile phones, that need more power or for fast charging. To shave time off development and cost when changing from single-cell to two-series cell architectures, these are USB-... » read more
