DESCRIPTION

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

In PSR mode, the MP6005 senses the third winding waveform on the primary side to regulate the output and save the optocoupler and TL431 feedback circuit from SSR application. Continuous conduction mode (CCM) provides high efficiency under heavy load conditions, while the output diode compensation function supports good output regulation even during primary-side regulation. In SSR mode, the SYNC driver provides high efficiency for active-clamped forward topology.

The MP6005 includes a 2A gate driver, frequency dithering, overload protection (OLP), and over-voltage protection (OVP).

The MP6005 is available in an MSOP10 package.
