MPX2002GYT-P

Power Supply Controllers, Monitors Overview

The MPX2002GYT-P is an all-in-one flyback controller from Monolithic Power Systems, integrating primary driving circuitry, secondary control, and synchronous rectification. It combines primary-side regulation with secondary-side benefits, eliminating the need for an external feedback circuit to reduce BOM cost. The device supports CCM, QR, PFM, and burst modes, with a fixed 20kHz switching frequency in burst mode to prevent audible noise. It features an internal linear regulator for SR power supply, enabling low-voltage operation without auxiliary windings.
