MP44018-AGS-Z

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. MP44018A is available in SOIC-8 package. Applications include LCD and OLED TVs, desktop PCs and servers, high power supply for lighting, AC/DC adapters, open frame SMPS and video game consoles.

• Valley turn-on for minimum switching loss
• Frequency reduction to reduce switching loss under light-load conditions
• Low supply current in burst mode, soft-on/off burst for low audible noise
• Mains compensation, improved THD
• Open/short pin protection, soft start-up
• Enhanced dynamic response
• VCC undervoltage lockout (UVLO) and overtemperature protection (OTP
• Brown-in (BI) and brownout (BO), static OVP
• Undervoltage protection (UVP), overcurrent protection (OCP)
• Overvoltage protection (OVP), overcurrent limit (OCL)
