1D14C_S3UP & 1D14C_D3UP Series
1W - Single/Dual Output DC-DC Converter - Fixed Input - Isolated & Unregulated
DC-DC Converter
1 Watt
The 1D14C_S3UP & 1D14C_D3UP Series are specially designed for applications
High efficiency up to 81%
High density, high stability
3000VDC Isolation
Temperature range:
-40°C ~ +105°C
where an isolated voltage is required in a distributed power supply system.
No external component
required
These products apply to:
DIP package
1) Where the voltage of the input power supply is fixed
(voltage variation ≤ ±10ꢀ)
Meet EN60950, UL60950
Short circuit protection (SCP)
Industry standard pinout
RoHS compliance
2) Where isolation is necessary between input and output
(isolation voltage ≤3000VDC)
3) Where the output voltage regulation and the ripple & noise of the output
voltage is not strictly required;
Typical application: digit circuit condition; normal low-frequency artificial
circuit condition; relay drive circuit and data switching circuit condition, etc..
