Monolithic Power Systems, Inc. PFC (Power Factor Correction) MP44014GS-Z

The MP44014GS-Z is a boundary conduction mode power factor correction (PFC) controller designed for high-performance applications with minimal external components. It features a high-performance voltage mode amplifier that accurately regulates output voltage and includes adjustable output over-voltage protection to enhance system reliability. The device operates with an ultra-low start-up current of 15OºA and a quiescent current of 0.46OºA under over-voltage protection conditions, contributing to its overall efficiency. This PFC controller supports a peak gate drive current of -750mA to +800mA and incorporates an on-chip R/C filter on the current sense pin, potentially eliminating the need for external filtering components. The MP44014GS-Z is housed in a compact SOIC-8 package, making it suitable for various applications, including offline adapters, electronic ballasts, and LLC front-end systems. It adheres to RoHS directives, ensuring compliance with environmental standards.
