MP44019

CrM/DCM Multi-Mode PFC Controller with Second OVP

Description

The MP44019 is a CrM/DCM multi-mode PFC controller that provides simple and high-performance active power factor correction using a minimal number of external components.

The MP44019 features a very low supply current that allows the device to achieve low standby power loss. The typical no-load power loss is below 50mW.To improve light-load efficiency, dead time extension technology is utilized to reduce the switching frequency under light loads.

The device achieves lower total harmonic distortion (THD) due to variable on time control in discontinuous conduction mode (DCM), when compared to conventional constant-on-time (COT) control.

Multi-protection functionality enhances the safety and reliability of the system. The MP44019 provides over-voltage protection (OVP), second OVP (OVP2), over-current limit (OCL), over-current protection (OCP), under-voltage protection (UVP), brown-in (BI) and brownout (BO), VCC under-voltage lockout (UVLO), and over-temperature protection (OTP).

The MP44019 is available in an SOIC-8 package.
