Pin-Out Information

(5.4W)

The PT4240 power modules are a

series of DC/DC converters housed in

an ultra-low profile (8mm) solderable

copper case. The series includes a num-

ber of preset output voltages ranging

from 1.3V ^†up to 12V, all fully approved

forTelecomuse. T heymayalsobeused

in many other applications that require

input-output isolation over an extended

temperature range. The modules are an

ideal choice for low-power digital and

analog circuits, including DSPs and

microcontrollers. The flexibility of

input-output isolation also allows the

output to be configured for negative

voltage operation.
