Product Information

The MP44018A is a CrM/DCM multi-mode PFC controller that provides simple and high-performance active power factor correction using minimal external components.

The MP44018A features a very low supply current. This 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.

Multi-protection functionality largely enhances the safety and reliability of the system. The MP44018A feature over-voltage protection (OVP), over-current limit (OCL), over-current protection (OCP), under-voltage protection (UVP), brown-in (BI) and brownout (BO), static OVP, VCC under-voltage lockout (UVLO), and over-temperature protection (OTP).

MP44018A is available in SOIC-8 package.

Advantages Include:

  • CrM/DCM multi-mode operation, small-size PFC controller
  • Improved light-load efficiency, >95% at 50% load
  • No-load power <30mW
  • Multi-protection function
  • Low THD
