The EVXG2101-2B-G44100-1A-00A is an evaluation board designed to demonstrate the capabilities of the MPXG2101x-2B and the MPG44100-1A. The evaluation board comes in a small form factor with high power density. The evaluation board’s electrical specifications make it well-suited for cell phone and notebook adapters. The EVXG2101-2B-G44100-1A-00A provides very low, no-load power consumption (<50mW), and its high overall efficiency meets DOE Level VI and CoC Tier 2 standards. It can also meet IEC 61000-3-2 Class-D harmonics current limits.

The MPXG2101 series belongs to the NovoOne family, which are all-in-one flyback regulators with an integrated primary GaN-compliant driving circuit and GaN HEMT, secondary controller, secondary ideal diode, and safety-compliant feedback. It offers the benefits of both primary side regulation (PSR) and secondary-side regulation (SSR).

By adopting capacitive isolation technology, the optocoupler used to communicate between the primary side and secondary side is not required.

The NovoOne family achieves adaptive zero-voltage switching (ZVS) to minimize switching frequency (f_SW) losses using patented synchronous rectifier (SR) ZVS control, eliminating the need for a dedicated ZVS circuit. This allows for high-frequency designs across the universal input range. The SR can match the primary-side MOSFET’s driving signal, which allows for safe SR operation.

The NovoOne family implements a peak power function that allows a smaller transformer to be used when compared to conventional quasi-resonant (QR) and ZVS control.

The MPG44100 is a quasi-resonant, critical conduction mode (CrM)/discontinuous conduction mode (DCM), multi-mode power factor correction (PFC) regulator with an integrated GaN FET. It provides simple and high-performance active power factor correction using minimal external components. The MPG44100 also integrates current-sensing and eliminates external sense resistors, which guarantee higher efficiency.

The EVXG2101-2B-G44100-1A-00A provides a reference design for a universal offline, isolated power supply with a 28V/5A, 20V/5A, 15V/3A, 9V/3A, or 5V/3A output. This datasheet contains the complete specifications for the power supply, a detailed circuit diagram, the entire bill of materials required to build the power supply, a drawing of the transformers, and performance testing data.
