1W isolated DC-DC converter Fixed input voltage, unregulated dual output

Description

A0303S-1WR2 is designed for use in distributed power supply systems and especially suitable in applications such as pure digital circuits,low frequency analog circuits,relay-driven circuits and data switching circuits,where:

1.The voltage of the input power supply is relatively stable with a variation of±10%Vin or less; 2.An input to output isolation voltage of up to 1500VDC is necessary;

3.The requirement for a tight line and load regulation is not as strict.

Such as pure digital circuits,low frequency analog circuits,relay-driven circuits and data switching circuits.

FEATURES

High power density
Ultra compact SIP package
Operating ambient temperature range: -40℃ to +85℃
I/O isolation test voltage 1.5k VDC
No external component required
Industry standard pin-out
