0.75S4A_3RP series
0.75W - Single Output DC-DC Converter - Fixed Input - Isolated & Regulated
DC-DC Converter
0.75 Watt
The 0.75S4A_3RP series is specially designed for applications where a group of
polar power supplies are isolated from the input power supply in a distributed
power supply system on a circuit board.
Small footprint
Low temperature rise
Internal SMD construction
Meets UL62368, EN62368
standards
Compact SMD package
High efficiency up to 74%
3000VDC isolation
Temperature range:
-40°C ~ +85°C
These products apply to:
RoHS compliance
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 ≤3000VDC)
Short circuit protection (SCP)
Industry standard pinout
3) Where the regulation of the output voltage and the output ripple noise are
not demanding
Such as: digit circuit condition; normal low-frequency artificial circuit condition;
relay drive circuit condition, etc.
