1MD8A_3UP Series

1W - Single Output DC-DC Converter - Fixed Input - Isolated & Unregulated

DC-DC Converter

1 Watt

High Eﬃciency up to 81%

3000VDC Isolation

Temperature Range:

-40°C ~ +85°C

No External Component

Required

The 1MD8A_3UP series are specially designed for applications where a

group of polar power supplies are isolated from the input power supply

in a distributed power supply system on a circuit board.

Internal SMD Construction

Industry Standard Pinout

RoHS Compliance

No Heatsink Required

They apply to:

Short Circuit Protection

1) Where the voltage of the input power supply is ﬁxed

(Voltage variation ≤ 10ꢀ)

2) Where isolation is necessary between input and output

(Isolation voltage ≤3000VDC)

3) Where the regulation of the output voltage and the output ripple

noise are not demanding.

Such as: purely digital circuits, ordinary low frequency analog circuits,

and IGBT power device driving circuits.

Note:

1. Operation under minimum load will not damage the converter; However, they

may not meet all speciﬁcation listed, and that will reduce the life of product.

2. All speciﬁcations measured at Ta=25°C, humidity<75ꢀ, nominal input voltage

and rated output load unless otherwise speciﬁed.

3. Only typical models listed, other models may be diﬀerent, please contact our

technical person for more details.

4. In this datasheet, all the test methods of indications are based on corporate

standards.
