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.
