2S7B_6UP series
2W - Single/Dual Output DC-DC Converter - Fixed Input - Isolated & Unregulated
DC-DC Converter
2 Watt
The 2S7B_6U series meet reinforced insulation requirements. It is specially
designed for applications which require compact size, high isolation, low isola-
tion capacitor and low leakage current power.
Efficiency up to 84%
4200VAC/6000VDC isolation
SIP package
No external component
required
RoHS compliance
Reinforced insulation
The patient leakage current:
Max 2μA
Short circuit protection (3sec)
EN60601-1, ANSI/AAMI
ES60601-1 approved
(1 x MOPP/2 x MOOP)
These products apply to:
1) Where the voltage of the input power supply is fixed
(voltage variation ≤ 10%)
Industry 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.
