Product Description: DC-Converter 105-3.3

The 105-3.3 is a classic non-isolated POL converter (3.3V Point of Load DC/DC converter) and it is mostly used on “motherboards” with DC supply voltages of 5V, 12V or 24V to generate the local 3.3VDC. An astonishing high efficiency characterizes the DC/DC converter in the Dil24 package even from 24V to 3.3V. The 3.3V output voltage can also be generated reliably with an input-side 5V supply voltage. Customer-specific adjustments in the output voltage down to 0.8V are possible at any time.
