3D8W_1.5RP series
3W - Single Output DC-DC Converter - Wide Input - Isolated & Regulated
DC-DC Converter
3 Watt
The 3D8W_1.5RP Series is specially designed for applications where a wide range
input voltage power supplies are isolated from the input power supply in a distri-
buted power supply system on a circuit board.
Wide input range (2:1)
Ultra compact DIP package
1.5kVDC isolation
Operating temperature range:
-40°C ~ +85°C
International standard pinout
No external component
required
High efficiency up to 80%
RoHS Compliance
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 Voltage ≤1500VDC);
Short circuit protection (SCP)
EN62368, UL62368 Approved
3) Where the regulation of the output voltage and the output ripple noise are
demanded.
The ultra-small volume design makes the converters an ideal solution for commu-
nications, instrumentation and industrial electronics applications.
