MP110

900V Offline Switching Regulator

DESCRIPTION

The MP110 is a flyback regulator with an

integrated 900V MOSFET. Requiring a minimum

number of external components, the MP110

provides excellent power regulation in AC-DC

applications that require high reliability. These

applications

include

smart

meters,

large

appliances,

industrial

controls

and

products

powered by unstable AC grids.

The regulator uses peak current mode control to

provide excellent transient response and easy

loop compensation. When the output power falls

below a given level, the regulator enters burst

mode to lower the stand-by power consumption.

The MPS proprietary 900V monolithic process

enables an over temperature protection (OTP)

that is on the same silicon of the 900V power

FET, offering the most precise thermal protection.

It also offers a full suite of protection features

protection, over-voltage protection, and short-

circuit protection.

The

MP110

is

designed

to

minimize

electromagnetic

interference

for

wireless

communication in home and building automation

applications.

The

operating

frequency

is

externally programmed with a single resistor so

that the power supply’s radiated energy can be

designed to avoid the interference to wireless

communication.

In addition to the programmable frequency, the

MP110 employs a frequency jittering function that

not only greatly reduces the noise level, but also

reduces the cost of EMI filter.

The MP110 is available in the PDIP8-7EP

package.
