Notes:

5. Line regulation is specified for VIN = 85 to 264 VAC.

6. Load regulation is specified for IOUT = 10% to 100%.

7. It is recommended that a fuse be used on the input of a power supply for

protection. For the MCP-02x series, a 1.2A slow blow fuse should be used.

The MCP-02x operates in constant voltage

mode (the same as most AC/DC power

supplies) to the point where the maximum

output current ratings shown in the tables

above are exceeded. When this happens,

the typical constant voltage regulated

supply will go into current limit and shut

down. Unlike conventional current limited

designs, the MCP-02x cannot be over-

loaded. As shown in the graph above, the

unit will switch to constant power mode and

will continue to supply power to the load.

This transition from “constant voltage

mode“ to “constant power mode” makes

the MCP-02x especially suitable for applica-

tions where current limited designs require

“oversizing” the power source to avoid

start-up issues. They are well suited for

applications that include driving or charging:

•

Mechanical Relays

•

Solenoids

•

Super Caps

•

LEDs

•

High Capacitive Loads

•

Solid State Relays

•

Op Amp Drivers

reaches the “current limit” level. At this

point, it transitions to constant power mode.

This output cannot be overloaded.

Typical Connection

The MCP-02x is designed to be used in industrial/commercial applications where they are connected

directly to the power mains. Mains connected components/equipment may be subjected to a wide

variety of surge/transient line disturbances. Input line disturbances are covered by the international

standards EN-61000-4-2,3,4,5.

The MCP-02x series is designed to meet the requirements of EN 61000-4 as shown on page one

of this datasheet. For applications that require a higher level of immunity to line disturbances, the

addition of external protection components (as shown in the diagram above) may be sufficient.
