1S7E_1.5UP Series
1W - Dual/Single Output DC-DC Converter - Fixed Input - Isolated & Unregulated
DC-DC Converter
1 Watt
The 1S7E_1.5UP series is specially designed for applications where an isolated
Ultra compact SIP Package
Efficiency up to 80%
Low Isolation Capacitance
1500VDC Isolation Voltage
Internal SMD Construction
Operating Temperature:
-40°C to +105°C
voltage is required in a distributed power supply system.
Industry Standard Pinout
RoHS compliance
These products apply to:
1) Where the voltage of the input power supply is stable
(voltage variation ≤ 10ꢀ%in)
Short circuit protection (SCP)
2) Where isolation is necessary between input and output
(isolation voltage ≤1500%DC)
3) Where the regulation of the output voltage and the output ripple noise
are not demanding
Such as: purely digital circuits, ordinary low frequency analog circuits, and data
switching circuits.
