2S4E_1U series
2W - Single Output - Fixed Input - Isolated & Unregulated
MINIATURE SIP PACKAGE
DC-DC Converter
2 Watt
The 2S4E_1U series are specially designed for applications where a single power
supply is isolated from the input power supply in a distributed power supply
system on a circuit board.
Efficiency up to 88%
Small footprint
SIP package
Single output voltage
1kVDC Isolation
Temperature Range:
-40°C~+85°C
Industry standard pinout
UL94-V0 Package
No heat sink required
EMI Complies With EN55022
Class B
These products apply to:
1) Where the voltage of the input power supply is fixed (voltage variation ≤ 10ꢀ)ꢁ
2) Where isolation is necessary between input and output
(isolation voltage = 1000VDC)
Low ripple and noise
3) Where the regulation of the output voltage and the output ripple and noise are
not demanding.
Such as: purely digital circuits, ordinary low frequency analog circuits and IGBT
power device driven circuits, etc.
