Spire Corp. 1 Introduction 1.1 Scope This specification defines the performance and characteristic for the model of SP-ATX-650WTB-PFC-1 power supply. 1.2 General Description SP-ATX-650WTB-PFC-1 is a switching power supply, 650W self-contained, AC to DC power source supply suitable for mounting in PC. 1) SPCC 0.8MM ENCLOSURE 2) ONE 12CM FAN 3) Black Paint Case 4) Dimensions:140mm(L)X150mm(W)X85mm(H) 2 Electrical 2.
Spire Corp. 2.1.2 Inrush Current Limiting Maximum inrush current from power-on (with power on at any point on the AC sine) and including, but not limited to, three line cycles, shall be limited to a level below the surge rating of the input line cord, AC switch if present, bridge rectifier, fuse, and EMI filter components. Repetitive ON/OFF cycling of the AC input voltage should not damage the power supply or cause the input fuse to blow. 2.1.
Spire Corp. 2.2.2 Output DC Current Ranges All outputs are within the specified limits of regulation when each output is subjected to the conditions listed below. Table 3. DC Input Line Requirements Minimum Maximum DC Nominal Voltage Current Current +12 V1 DC 2A 18A +12 V2 DC 2A 18A +5 V DC 1A 30A +3.3 V DC 1A 28A - 12 V DC 0.0 A 0.8A +5 V SB 0.0 A 2.5A NOTE: 1)The combined power output of +5V and +3.3V shall not exceed 220W. The combined power output of +5V,+3.
Spire Corp. 2.2.6 Output Ripple/Noise The output ripple/noise requirements listed in Table 5 should be met throughout the load ranges specified and under all input voltage conditions as specified. Ripple and noise are defined as periodic or random signals over a frequency band of 10 Hz to 20MHz. Measurements shall be made with an oscilloscope with 20 MHZ bandwidth. Outputs should be bypassed at the connector with a 0.1μF ceramic disk capacitor and a 10μF electrolytic capacitor to simulate system loading.
Spire Corp. 2.2.7 Output Transient Response The table below summarizes the output transient steps for each output. The Transient slew rate is =0.5A/μs. Table 6. DC Output Transient Response Specifications DC Output Maximum Step Size Output Voltage Tolerance +12V1DC +12V2DC +5VDC +3.3VDC -12VDC +5VSB 40% of rated output 60% of rated output 30% of rated output 30% of rated output 0.1A 0.5A ±5% ±5% ±5% ±5% ±10% ±5% 2.2.
Spire Corp. 2.2.11 Voltage Hold-up Time All output will stay within regulation for at least 16ms after an AC line voltage failure is detected at nominal line (230VAC) under full load condition. 2.3 Timing / Housekeeping / Control Figure 2.

Spire Corp. 2.3.2 PS_ON# The power supply provides an internal pull-up to TTL high. The power supply also provides denounce circuitry on PS_ON# to prevent it from oscillating on/off at startup when activated by a mechanical switch. The DC output enable circuitry is SELV-complaint. Table 8. PS_ON# Signal Characteristics VIL, Input Low Voltage VIL, Input Low Current (Vin = 0.4 V) VIH, Input High Voltage (lin = -200 μA) VIH, open circuit, lin = 0 Min. Max. 0.0V 0.8V -1.6mA 2.0V 5.25V 2.3.
Spire Corp. 2.4 Output Protection Each DC output is protected from over voltage, over current and short circuit. The following sections include the details for these protection mechanisms. 2.4.1 Over voltage Protection The overvoltage sense circuitry and reference reside in packages that are separate and distinct from the regulator control circuitry and reference. No single point fault is able to cause a sustained overvoltage condition on any or all outputs.
