EPIC2ACB04 + EPIC2ACQ07

Bundle for PD USB-C 3.1 applications

The Eggtronic Totem-Pole + QuarEgg® bundle (featuring the EPIC2ACB04 and EPIC2ACQ07 controllers) delivers an advanced power conversion architecture that combines bridgeless Power Factor Correction (PFC) with proprietary QuarEgg® isolated ZVS converter. This dual-controller setup operates seamlessly to provide a highly efficient AC/DC converter. The primary-side controller (EPIC2ACB04) seamlessly manages both the active Totem-Pole front-end and the main QuarEgg switching stage, while the secondary-side companion controller (EPIC2ACQ07) handles Synchronous Rectification (SR), precise output voltage regulation, and USB Power Delivery (PD) 3.1 protocol management.

The EPIC 2.0 is a cost-optimized family of controllers, suitable for power conversion applications, offering high power levels, high efficiency over the entire span of loads and inputs, and reduced Bill of Materials.

The QuarEgg® bundle is best suited for high-efficiency single ports power adapters that require a Power Delivery (PD) 3.1 protocol. Such as laptops, smartphones, tablets and any portable devices with USB-C interface. It enables a total peak efficiency of >95%, high power density and reduced BOM.

Thanks to EPIC 2.0 RISC-V digital core with Eggtronic’s QuarEgg® proprietary control algorithms, and a rich set of digital and analog peripherals, it provides a highly flexible and scalable hardware platform, enabling extreme performance and cost effective solutions.
