DC-DC Converter
DC-DC Converter
1 Watt
Wide 2:1 Input Voltage Range
High Efficiency up to 81%
1W Single and Dual outputs
I/O Isolation 2KVDC, 4KVDC
and 5,2KVDC
Operating Temperature
Range: -40°C to +100°C
Continuous Short Circuit
Protection (SCP)
The 1S8W_S & 1S8W_D series are specially designed for applications
where a wide range input voltage power supplies are isolated from the
input power supply in a distributed power supply system on a circuit
board.
Remote ON/OFF Control
These products apply to:
1) Where the voltage of the input power supply is wide range
(voltage range≤2:1)
2) Where isolation is necessary between input and output (isolation
voltage≤2000VDC/4000VDC/5200VDC)
3) Where the regulation of the output voltage and the output ripple
noise are demanded
