Ordering Information

Pin Function

PT 4121r = 3.3V/5A (16.5W)

PT 4122r = 5.0V/4A

The PT4120 power modules are a series

of isolated DC/DC converters housed a low-

profile package. Rated for 20 watts or 5A, the

series includes standard output voltages rang-

ing from as low as 1.5VDC to 15VDC. The

output may be adjusted 10% of nominal.

These converters are ideal for Telecom,

Industrial, Computer, and other distributed

power applications that require input-to-

output isolation.

† For further information, see

application notes.

Using multiple PT4120 modules, system

designers can implement a complete custom

power supply solution. The flexibility of full

isolation also allows the input or output to be

configured for negative voltage operation.

The PT4120 series requires no additional

components for proper operation.
