PWR70C Series
3 Watt, High Isolation, Unregulated DC/DC Converters
PRODUCT OVERVIEW
The PWR70C is a dual-output DC/DC converter designed for general purpose
power conversion applications where high ef?ciency is more important than load
regulation.
The PWR70C provides a bipolar output voltage approximately equal to the input
voltage magnitude. It operates over an input voltage range of 10VDC to 18VDC.
Isolation voltage is tested at 5000Vpk.
Six-sided shielding suppresses electromagnetic radiation which could disturb
sensitive analog measurements or interfere with system timing signals. Input
?ltering minimizes re?ected ripple current. Output ripple voltage and switching
transients are reduced by ?ltering the PWR70C outputs.
The PWR70C is tested in compliance with UL544, VDE750, and CSA C22.2
dielectric withstand voltage requirements.
