Description
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 鹵10% of nominal.
These converters are ideal for Telecom,
Industrial, Computer, and other distributed
power applications that require input-to-
output isolation.
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.
