PT4521r = 3.3V/5A (16.5W)

PT4522r = 5.0V/4A

The PT4520 Excalibur™ power modules

are a series of isolated DC/DC converters

housed a new space-saving copper case. The

series includes a number of standard output

voltages ranging from as low as 1.2VDC to

15VDC, each adjustable by up to 10% of

nominal. The modules are ideal for Telecom,

Industrial, Computer, and other distributed

power applications that require input-to-output

isolation.

PT4523r = 12V/1.6A

PT4524r = 15V/1.3A

PT4526r = 1.5V/5A (7.5W)

PT4527r = 1.8V/5A (9W)

PT4528r = 2.5V/5A (12.5W)

PT4529r = 1.2V/5A (6W)

Package

Using multiple 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 PT4520 series is electrically equivalent

to the popular PT4120 series and requires no

additional components for proper operation.
