PRODUCT OVERVIEW

The MEV3 series is a new range of high

performance 3W DC/DC converters, offering 3W

of available output power in a previously rated

2W package capable of operation over the full

industrial temperature range of -40ºC to 85ºC.

Available in an industry standard SIP package,

with a pin compatible power upgrade path from

the 1W NMV/MEV and 2W NMK series’, they

are ideally suited for providing local supplies on

control system boards with the added beneﬁt of

3kVDC galvanic isolation.

FEATURES

n UL 60950 recognised

n RoHS compliant

n Typical efﬁciency from 83%

n Power density 1.9W/cm

n Wide temperature performance at full

3 Watt load, –40°C to 85°C

n UL 94V-0 package material

n No heatsink required

n Industry standard pinout

n 3kVDC isolation (1 minute)

n 5V & 12V input

n 5V, 9V, 12V, & 15V output

n Fully encapsulated with toroidal

magnetics

n No external components required

n No electrolytic or tantalum capacitors

1. See Ripple & Noise characterisation method.

2. Calculated using MIL-HDBK-217F FN2 with nominal input voltage at full load.

All speciﬁcations typical at T

A=25°C, nominal input voltage and rated output current unless otherwise speciﬁed.

MEV3 Series 3kVDC Isolated 3W Single Output DC/DC Converters APPLICATION NOTES Minimum load The minimum load to meet datasheet specification is 10% of the full rated load across the specified input voltage range. Lower than 10% minimum loading will result in an increase in output voltage, which may rise to typically double the specified output voltage if the output load falls to less than 5%.

MEV3 Series 3kVDC Isolated 3W Single Output DC/DC Converters APPLICATION NOTES (continued) Output Ripple Reduction By using the values of inductance and capacitance stated, the output ripple at the rated load is lowered to 5mV p-p max. Component selection Capacitor: It is required that the ESR (Equivalent Series Resistance) should be as low as possible, ceramic types are recommended. The voltage rating should be at least twice (except for 15V output), the rated output voltage of the DC/DC converter.
