2 1 ORDERING INFORMATION PET N A Product Family PET Power Level 750 W Dash V1 Output 12 V Dash Width 50 mm Airflow N: Normal R: Reversed Input A: AC 2 OVERVIEW The PET NA AC-DC power supply is a mainly DSP controlled, highly efficient front-end. It incorporates resonance-soft-switching technology and interleaved power trains to reduce component stresses, providing increased system reliability and very high efficiency. With a wide input operating voltage range and no derating of output power with input voltage and temperature, the PET NA maximizes power availability in demanding server, switch, and router applications. The front-end is fan cooled and ideally suited for server integration with a matching airflow path. The PFC stage is controlled using a state-of-the-art integrated control-ic to guarantee best efficiency and unity power factor over a wide operating range. The DC-DC stage uses soft switching resonant techniques in conjunction with synchronous rectification. An active OR-ing device on the output ensures no reverse load current and renders the supply ideally suited for operation in redundant power systems. The always-on standby output with voltage level (5V) provides power to external power distribution and management controllers. Its protection with an active OR-ing device provides for maximum reliability. Status information is provided with front-panel LED. In addition, the power supply can be controlled and the fan speed set via the I 2 C bus. It allows full monitoring of the supply, including input and output voltage, current, power, and inside temperatures. Cooling is managed by a fan controlled by the DSP controller. The fan speed is adjusted automatically depending on the actual power demand and supply temperature and can be overridden through the I 2 C bus. 3 INPUT FEATURES 3.1 GENERAL PARAMETER DESCRIPTION / CONDITION MIN NOM MAX UNIT Vi nom Nominal Input Voltage VAC Vi Input Voltage Ranges Normal operating (Vi min to Vi max) VAC Ii max Max Input Current 4 9 Arms Ii p Inrush Current 1 35@115VAC Vi min to Vi max, 90, TNTC=25 C 70@240VAC Fi Input Frequency Hz Ap 3.2 INPUT POWER FACTOR CORRECTION (ACTIVE PFC) The power factor at 100% of rated load shall be 0.95 at nominal input voltage and full load. 3.3 AC LINE TRANSIENT SPECIFICATION AC line transient conditions are characterized as sag and surge conditions.

Low pass filter (104 capacitor is recommended) shall be added into the PW_OK signal to suppress the high frequency noise to keep the high level absolutely. However, this low pass filter shall be used in PSU or motherboard PW_OK circuit. Therefore, supplier must be subject to add this low pass filter in the PW_OK input circuit of motherboard if it cannot be added in PSU circuit due to the re-layout difficulty. 6.3 PS_ON# SIGNAL PS_ON# signal is required to remotely turn on/off the power supply module / PDB Combo. PS_ON# is an active low signal that turns on the +12V power rail and other DC to DC converters on the PDB. When this signal is not pulled low by the system, or left open, all the outputs (except for 5VSB) shall be turned off. Refer to Figure 1 On/Off Timing for timing diagram. PET NA 6
