Pin Function

PT 4141r = 3.3V/5A (16.5W)

PT 4142r = 5.0V/4A

The PT4140 power modules are a series

of isolated DC/DC converters housed in a

low-profile package. Rated for 20 watts or 5A,

the series includes standard output voltages

ranging from as low as 1.5VDC to 15VDC.

The output may be adjusted up to 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 PT4140 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 PT4140 series requires no additional

components for proper operation.
