QT8B_3UP Series

0.25W - Single Output DC-DC Converter - Fixed Input - Isolated & Unregulated

DC-DC Converter

0.25 Watt

3000VDC isolation

Industry standard pinout

RoHS Compliance

The QT8B_3UP miniature surface mounted DC-DC converters series are

an ideal and economical solution for many applications where noise

reduction, voltage isolation, voltage conversion in distributed power

systems is required. These converters are qualiﬁed for the higher tempe-

ratures requested by lead-free reﬂow solder processes, especially for

automated SMD production lines.

Eﬃciency up to 78%

Operating temperature

range: -40°C ~ +105°C

Power density 1.8W/cm³

Short circuit protection (SCP)

Small footprint

(over pins 1.37cm²)

These products apply to:

1) Where the voltage of the input power supply is ﬁxed

(Voltage variation ≤ 10ꢀ)

2) Where isolation is necessary between input and output

(Isolation voltage ≤3000VDC)

3) Where the regulation of the output voltage and the output ripple

noise are not demanding.
