3DAW4 Series
3W - Single Output - Wide Input - Isolated & Regulated
DC-DC Converter
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;
