1S7B_6U Series
1W - Single/Dual Output DC-DC Converter - Fixed Input - Isolated & Unregulated
DC-DC Converter
1 Watt
The 1S7B_6U series meet basic insulation grid supplied circuits from earthed expo-
sed parts and is thus vital for safety. It is specially designed for applications which
require compact size, high isolation, low isolation capacitor and low leakage cur-
rent power.
High efficiency up to 85%
6000VDC isolation voltage
Protective separation
insulation
No external component
required
RoHS compliance
Internal SMD construction
Unregulated output types
These products apply to:
7 PIN SIP package
1) Where the voltage of the input power supply is fixed
(voltage variation ≤ 10%)
Industry standard pinout
2) Where isolation is necessary between input and output
(isolation voltage ≤6000VDC)
3) Where do not has high requirement of line regulation and the ripple & noise of
the output voltage;
Such as: Medical collection and isolation, High voltage collection circuit, IGBT-
driven circuits, etc.
