PT42/4300 Series
Wide Input Voltage Range: 38V to 72V
83% Efficiency
1,500 VDC Isolation
18 Pin DIP Package
3.5 Million Hour MTBF
Meets FCC/EN55022 Class A
UL and CSA approved
No External Components Required
Adjustable Output Voltage
The PT4200 series of isolated DC/DC
converters advance the state-of-the-art for
board-mounted converters by employing
high switching frequencies, thick-film technol-
ogy and a high degree of silicon integration.
The high reliability and very low package
height makes these converters ideal for
Telecom and Datacom applications requiring
input-to-output isolation with board spacing
down to 0.6”.
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 ±5V, +5V/+3.3V, and
±12V.
