7.5DAW_2 series
7.5W - Single/Dual Output - Ultra Wide Input - Isolated & Regulated
DC-DC Converter
DC-DC Converter
7.5 Watt
Wide 2:1 input voltage range
DIP24 package metal case
(Suffix „/M“ ) and plastic
case options
5 side shielded metal case
High efficiency up to 87%
7.5W single and dual outputs
I/O isolation 2kVDC and
3kVDC option
The 7.5DAW_2 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.
Operating temperature range
-40°C to +75°C
Continuous short circuit
protection (SCP)
Remote ON/OFF control option
(„A“ pinning only)
These products apply to:
1) Where the voltage of the input power supply is wide range
(voltage range ≤ 2 :1);
2) Where isolation is necessary between input and output
(isolation ≤2000VDC, ≤3000VDC);
3) Where the regulation of the output voltage and the output ripple
noise are demanded.
