3DAW4 Series

3W - Single Output - Wide Input - Isolated & Regulated

DC-DC Converter

3 Watt

The 3DAW4 series are specially designed for applications where a wide

range input voltage power supplies are isolated from the input power

supply in a distributed power supply system on a circuit board.

4:1 wide input voltage range

Operating temperature:

-40°C to +85°C

UL94-V0 package

No external component

required

1500VDC isolation

Short circuit protection, SCP

(automatic recovery)

Industry standard pinout

MTBF>1,000,000 hours

RoHS compliance

These products apply to:

1) Where the voltage of the input power supply is wide range

(voltage range≤ 4:1);

Internal SMD construction

2) Where isolation is necessary between input and output

(isolation≤1500VDC);

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

noise are demanded.

1. The min. load shall be no lower than 5ꢀ, or the output ripple may increase

rapidly; If the product is operated under the min. required load, the product

performance cannot be guaranteed to comply with all performance indexes in the

Manual, but the reliability of the product will not be inﬂuenced;

2. The max. capacitive load should be tested within the input voltage range and

under full load conditions;

3. Unless otherwise speciﬁed, data in this datasheet should be tested under the

conditions of Ta=25 , humidity<75ꢀ when inputting nominal voltage and output-

ting rated load;

4. All index testing methods in this datasheet are based on our Company’s corpo-

rate standards;

5. The performance indexes of the product models listed in this datasheet are as

above, but some indexes of non-standard model ¿≠ products will exceed the above-

mentioned requirements, and please directly contact our technicians for speciﬁc

information;
