TPR-W25 Series
DESCRIPTION 0.25W 3KVDC Isolated Single Output DC/DC Converters
The TPR-W25 series are miniature, isolated 0.25W DC/DC converters in a SIP package. They
offer the ideal solution in many space critical applications for board level power distribution.
The internal SMD construction makes it possible to offer a product with high performance at
low cost. The series offers smaller size, improved efficiency, lower output ripple noise and
3KVDC isolation.

DESIGN REFERENCE
Typical application circuit
If it is required to further reduce input and output ripple, a filter capacitor may be connected to the input and output terminals, see Fig.1Moreover, choosing a suitable
W
filter capacitor is very important, start-up problems may be caused if the capacitance is too large. Under thecondition of safe and reliable operation, the
recommended capacitive load values are shown in Table 1.
