NOTE
1. di/dt= 0.1A/1uS, Vin=48V,Tc=25°C; load change =0.5 Io
max. to 0.75 Io max. and 0.75 Io max. to 0.5 Io max.
2. Measured with 10uF tantalum capacitor and 0.1uF & 1uF
ceramic capacitor across output.
3. Measured from high line to low line.
4. Measured from full load to 1/4 load.
5. Maximum capacitive load across the output ports should
not over following indicated values.
6. This converter required a minimum 10% loading on the
output to maintain specified regulation. Operation under
no-load condition will not damage these devices,
However they may not meet all listed specification.
7. Standard product is active low, active high remote on/off
option is available, to order suffix a “H” to the model
number e.g. UM3211H
STANDARD REMOTE ON/OFF CONTROL
Logic Compatibility………………………………………..
……………………….CMOS or Open Collector TTL
Ec-OFF …..………………... > +2.5 VDC or Open Circuit
Ec-ON ……..……………………………….….< 0.8 VDC
Control Common …………. Referenced to Input Minus
EXTERNAL OUTPUT TRIMMING
Output may optionally be externally trimmed (±10%) with a fixed
resistor or an external trimpot as shown.
