ATX DC-DC Converter Series
Input Requirements: 12V regulated, min=2A, max=10A (load
dependent). Over-voltage shutdown will occur at ~13-13.5V.
Size: 44.5mm(L) * 20mm(W) * 30mm (H) (1U compliant)
Weight: 45gramms, including cable harness, 20 grams without cable
harness.
DC-Jack: Female, panel mount, 2.5*5.5*10 mm.
Connectors
Molex 39-01-2200 compatible, two 3.5” drive power connectors (PATA
and SATA) and one P4-12V 4 connector (mini-fit JR 4p). Header and
mating connector for the removable cable harness can be found at:
Overload protection
Over load protection will be effected when either of the loads (+5V &
+3.3V) exceeds > 200% Max Load.
Turn-on Delay
After turning on, at least 20 ms will be needed for the rise of +5VSB
output voltage (measured from 10% to 95%) to reach its peak.
Remote ON/OFF control (PS_ON)
Logic level is LOW - Output voltage is enabled (PS_ON pin)
Logic level is HIGH - Output voltage is disabled (PS_ON pin)
PWR_GD
Logic level is low: PWR_GD=OK
Logic level is high: PWR_GD=not OK (10.5V<V(in)>13.5V or other
fault conditions)
Operating environment: Temperature: -20 to 85 degree centigrade.
NOTE: Thermal shutdown occurs at 105-115C.
Relative Humidity: 10 to 90 percent, non-condensing.
Efficiency, MTBF: 95%. MTBF=100K hours at 55Celsius.
Shipping and storage: Temperature -40 to +85 degree centigrade.
Relative humidity 5 to 95 percent, non-condensing
