Introduction
AV60A dual output series provides two inde-
pendent and fully regulated positive outputs,
the outputs are also separately trimmable. A
remote on/off feature is included as standard.
AV60A dual output isolated DC/DC converters
is built using the industry standard half-brick
pin-out and package 61.0mm x 57.9mm x
Features
1. Two independent positive outputs
2. Each output is separately trimmable
3. CNT function
4. High efficiency
5. High power density
6. Low output noise
7. Metal baseplate
12.7mm (2.4" x 2.28" x 0.5"). Typical efficien-
8. Input undervoltage protection
cies are 82% for the 5V/3.3V outputs, and 80%
for the 3.3V/2.5V outputs. The AV60A dual out-
put series is available with 2:1 input range of
36V-75V, and with output combination of
5V/3.3V and 3.3V/2.5V at maximum current of
15 Amps. The maximum current can be drawn
from either output, or in any combination, as
long as the total output current does not exceed
15 Amps. The output power is 75W. The input-
output isolation is 1500Vdc.
AV60A dual output series is designed to meet
CISPR22, FCC Class A, UL, TUV, and CSA
certifications.
9. Short circuit protection
10. Over current protection
11. Output overvoltage protection
12. Wide operating

NOTE:
The figure is Positive Logic Control,
if the CNT pin is left open, the converter will default to “control
on” operation.
Negative Logic Control is also available.
Positive Logic Control:
Low=Off,
Negative Logic Control:
Low=On,
High=On.
High=Off.
