1S7WB Series
1W - Single/Dual Output - Wide Input - Isolated & Regulated
SIP Package
DC-DC Converter
1 Watt
The 1S7WB 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
Short circuit protection (SCP)
RoHS Compliance
No external component
required
2:1 Wide input voltage range
High Efficiency up to 80%
Regulated output types
Internal SMD construction
These products apply to:
1) Where the voltage of the input power supply is wide range
(voltage range≤2:1)
Industry standard pinout
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:
3. In this datasheet, all the test methods of indications are based on corporate
standards.
1. Operation under minimum load will not damage the converter; However, they
may not meet all specification listed.
2. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage
and rated output load unless otherwise specified.
