IC Details

MPX2001 is all-in-one solution flyback controller. It integrates primary driving circuit, secondary controller and synchronous rectification driver in one chip. So it can keep all the benefit of both primary side regulation (PSR) and secondary side regulation (SSR) together. With MPX2001, system complexity can be reduced due to no feedback circuit is needed. Thus the total BOM cost is eventually reduced. At the same time, Synchronous Rectifier (SR) can be perfectly matched with the driving signal of the primary side MOSFET. With this feature, SR is able to operate safely in the Continuous Conduction Mode (CCM), which will potentially help to increase the overall efficiency and gain more flexibility to the design. MPX2001 features advanced protections, including primary sensed output Over Voltage Protection (OVP) and Primary Over Current Protection (POCP), real secondary sensed output Over Load Protection (OLP), Brown-in/Brown-out (B/O, B/I), Short Circuit Protection (SCP), Current-Sensing Short Protection (SSP), internal Thermal Shut Down (TSD), Under Voltage Locked-Out (UVLO), and External triggered Protection (Ext.P).
