2S7WB_3RP series
2W - Single/Dual Output - Wide Input - Isolated & Regulated
SIP Package
DC-DC Converter
2 Watt
The 2S7WB 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.
7PIN SIP package
Operating temperature:
-40°C to +85°C
2:1 Wide input voltage range
High Efficiency up to 80%
Regulated output types
Internal SMD construction
Short circuit protection (SCP)
RoHS Compliance
These products apply to:
No external component
required
Industry standard pinout
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 ≤3000VDC);
3) Where the regulation of the output voltage and the output ripple noise are
demanding.

Note:
1. Operation under minimum load will not damage the converter; However,
they may not meet all specification listed.
3. In this datasheet, all the test methods of indications are based on corporate
standards.
2. All specifications measured at Ta = 25°C, humidity <75%, nominal input
voltage and rated output load unless otherwise specified.
