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.
