MPX2003 All-in-One Flyback Controllers

Monolithic Power Systems (MPS) MPX2003 All-in-One Flyback Controllers offer an integrated primary driving circuit, secondary controller, synchronous rectification driver, and safety-compliant feedback. These flyback controllers provide an advantage over both Primary-Side Regulation (PSR) and Secondary-Side Regulation (SSR). The MPX2003 controllers can function in Continuous Conduction Mode (CCM) under heavy loads and then operate in Quasi-Resonant (QR) mode when the load decreases. The switching frequency (f_SW) in these controllers is fixed at 20kHz when the device enters burst mode, which can prevent audible noise. The MPX2003 controllers produce high efficiency under most load conditions while improving Electromagnetic Interference (EMI) performance.
