Flyback and Forward Controller with Primary-Side or Secondary-Side Regulation

The MP6005 from Monolithic Power Systems is a high power, high efficiency flyback and forward controller. It is specifically designed for both low cost, small size isolated solution with primary-side regulate (PSR) flyback application, and high efficiency secondary-side regulate (SSR) active-clamped forward application. It also can be used in SSR flyback topology.

MP6005 senses the third winding waveform on primary side to regulate output in PSR mode, saves the traditional complex opto-isolator circuit, while the continuous-conduction-mode in heavy load provides high efficiency. Diode voltage drop compensation function supports good output regulation even it adopts primary side regulate.

MP6005 can also be set as SSR mode, while the SYNC driver provides high efficiency solution for active-clamped forward topology.

The MP6005 also features with 2A gate driver, frequency dithering, over load protection and over voltage protection. The MP6005 is available in MSOP10 package.
