5.8 Power Supply (300 WATT)
5.8.1 Power Supply Specifications
This specification describes the requirements of 300Watts switching power supply with an FLEX-ATX form-factor and TFX 12V,+5V standby
voltage, remote on/off, dual line input capability.
AC INPUT
AC input requirements
The input voltage, current, and frequency requirements for continuous operation are stated below.
Parameter Min Nom Max Unit
Vin 90 100-240 264 VACrms
Vin Frequency 47 60-50 63 Hz
Lin(300W) 5---2.5 Arms
Power factor correction (PF)>0.9 at full load.
Inrush current regulation
The power supply must meet inrush requirements for any rated AC voltage, during turn on at any phase
Of AC voltage, during a single cycle AC dropout condition, during repetitive ON/OFF cycling of AC,
and over the specified temperature range (Top). The peak inrush current shall be less than the ratings of its critical components (including input
fuse, bulk rectifiers, and surge limiting device).
DC OUTPUT
DC voltage regulation
Parameter Range Min Nom Max Unit
+3.3v ±5% +3.14 +3.3 +3.47 Volts
+5V ±5% +4.75 +5.0 +5.25 Volts
+12V ±5% +11.4 +12.0 +12.6 Volts
-12V ±10% -10.8 -12.0 -13.2 Volts
+5VSb ±5% +4.75 +5.0 +5.25 Volts
1. When no load, +3.3V output v/-5% regulation limits do not apply.
2. When dynamic load, +12V regulation can to +/-10%
