1S7AE_1U series
1W - Single/Dual Output DC-DC Converter - Fixed Input - Isolated & Unregulated
DC-DC Converter
1 Watt
The 1S7AE_1U series meet reinforced insulation requirements. They are specially
designed for applications where require compact size, high isolation, low isolation
capacitor and low leakage current power. They are widely used in electricity, IGBT
drivers and so on.
High efficiency up to 86%
1000VDC isolation
SIP package
Operating temperature:
-40°C to +85°C
International standard pinout
EMI complies with EN55032
Class B
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.
