1S7AE_DS1U Series
1W - Dual separate Output DC-DC Converter - Isolated & Unregulated
DC-DC Converter
1 Watt
The 1S7AE_DS1U series are cost effective dual separate output DC-DC converters.
They are specially designed for applications where require compact size, high iso-
lation, low isolation capacitor and low leakage current power. They are widely
used in electricity, IGBT drivers and so on.
High efficiency up to 80%
1000VDC isolation
SIP package
Operating temperature:
-40°C to +85°C
International standard pinout
Low ripple and noise
Low ripple and noise
These products apply to:
1) Where the voltage of the input power supply is fixed (voltage variation ≤ 10%)
2) Where isolation is necessary between input and output
(isolation voltage 1000VDC)
3) Where do not has high requirement of line regulation and the ripple & noise of
the output voltage;
Such as: Collection and isolation, High voltage collection circuit, IGBT-driven cir-
cuits, etc.
