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.
