DESCRIPTION：

The TPT series are miniature, isolated 3W 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 1.5KVDC isolation and providing three

output voltages of -24V, -48V and -72V from a single isolated 4V, 5V and 12V input voltage.
