Adjustable Output Voltage
Power Trends鈥?PT4200 series of isolated
DC to DC converters advance the state-of-the-
art for board-mounted converters by employing
high switching frequencies, thick-film technology
and a high degree of silicon integration. The high
reliability and very low package height makes
these converters ideal for T
elecom and Datacom
applications requiring input-to-output isolation
with board spacing down to 0.6鈥?
The PT4200 series is offered in a unique
molded through-hole or SMD-DIP package
with single output voltages of 2V 3.3V, 5V, and
,
12V dual outputs of 鹵5V +5V/+3.3V, and 鹵12V.
