MPXG2101R-1BLGYT-Z

The MPXG2101 series is part of the NovoOne Family, which are all-in-one flyback regulators that integrate a primary GaN-compliant driving circuit, GaN HEMT, secondary controller, 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, which is used to communicate between the primary side and the secondary side, can be saved. The MPXG2101 series achieves adaptive zero-voltage-switching (ZVS) to minimize switching losses using patented SRZVS control, eliminating the need for a dedicated ZVS circuit. It allows for high-frequency design across a universal input range. The synchronous rectifier (SR) can match the driving signal of the primary-side MOSFET, meaning the SR can operate safely. This family is specifically designed to work with the power factor correction (PFC) stage and the peak power function, allowing for a smaller transformer and input bulk capacitor when compared to traditional quasi-resonant (QR) and ZVS control. The NovoOne family of ICs feature advanced protections, including short-circuit protection (SCP), VCC voltage (VCC) over-voltage protection (VCC OVP), internal brown-in/brownout (B/I, B/O), CS open protection (SOP), zero-current detection (ZCD) over-voltage protection and under-voltage protection (ZCD OVP/UVP), HV over-voltage protection (HV OVP), primary independent run timeout protection (PRTP), secondary run timeout protection (SRTP), secondary overload protection (SOLP), open-loop protection (FB OLP), VDD voltage (VDD) OVP (VDD OVP), under-voltage lockout (VCC UVLO, VDD UVLO, and VSR UVLO), internal thermal shutdown (POTP and SOTP), and external over-temperature protection (EOTP).
