MP44018A CrM/DCM Multi-Mode PFC Controller

Monolithic Power Systems (MPS) MP44018A CrM/DCM Multi-Mode PFC Controller provides simple and high-performance active Power Factor Correction (PFC) using minimal external components. The MP44018A features a very low supply current. This feature allows the device to achieve low standby power loss and the typical no load power is below 30mW. The switching frequency is reduced by dead time extension technology under light-load conditions, which improves light-load efficiency. The MP44018A also achieves lower THD due to variable-on-time control in Discontinuous Conduction Mode (DCM) when compared to conventional Constant-on-Time (COT) control.
