Monolithic Power Systems (MPS) EVX2002-44018A-00A Evaluation Board

Monolithic Power Systems (MPS) EVX2002-44018A-00A Evaluation Board evaluates the MP44018A and MPX2002 as a 120W, 2C1A adapter. The MPS MP44018A is a critical conduction mode (CrM)/discontinuous conduction mode (DCM) controller. The device enables efficient, high-performance active power factor correction (PFC) with minimal external components. The MP44018A features reduced switching frequency (fSW) through dead time (DT) extension technology for enhanced light-load efficiency. Additionally, the MP44018A achieves lower total harmonic distortion (THD) via variable-on-time control in DCM, surpassing conventional constant-on-time (COT) control.
