1S7B_6UP series
1W - Single/Dual Output DC-DC Converter - Fixed Input - Isolated & Unregulated
DC-DC Converter
1 Watt
The 1S7B_6UP series are specially designed for applications where an isolated
voltage is required in a distributed power supply system. They are suitable for:
pure digital circuits, low frequency analog circuits, relay-driven circuits and data
switching circuits.
High efficiency up to 80%
4200VAC/6000VDC isolation
SIP package
Operating temperature:
-40°C up to +85°C
RoHS compliance
Reinforced insulation
The patient leakage current:
Max 2μA
Short circuit protection
EN60601-1, ANSI/AAMI
ES60601-1 approved
(1 x MOPP/2 x MOOP)
Meets EN62368
These products apply to:
1) Where the voltage of the input power supply is fixed (voltage
variation ≤ 10%)
International standard pinout
2) Where isolation is necessary between input and output
(isolation voltage ≤4200VAC or 6000VDC)
3) Where do not has high requirement of line regulation and the ripple & noise
of the output voltage; such as: Medical collection and isolation, High voltage
collection circuit, IGBT-driven circuits, etc.
