Indicates to other modules in the system that all outputs are within their working level. Controls power supply outputs. This signal in conjunction with INHIBIT controls the outputs. Please refer to Table 1 Controls power supply outputs. This signal in conjunction with INHIBIT controls the outputs. Please refer to Table 1 Used for geographical addressing. GA1 is the most significant bit and GA0 is the least significant bit. I2C bus Clock and Data respectively. Through this bus the voltage and temperature readouts can be shared. The REF_CLK signal is used to allow the power supply frequency to sync with the system frequency. The SENSE is used to achieve accurate load regulations at load terminals (this is done by connecting the pins directly to the load s terminals). 9 LOAD SHARE Bidirectional Used for paralleling several M4065 units (M4065A Only).

6 Detailed Information 1. Outputs regulation The M4065 contains accurate internal sense lines to keep output voltage at less than 1.5% regulation for all Line/ Load and temperature range (see Table 2). For parallel configuration there is an extended regulation range in order to support the current sharing (see Table 3).

11 3.3Vaux Voltage 2 M4065 Input Voltage Operation. The M4065 steady state operation voltage is 18V to 36V and will have continuous work up to 50V Input line. During MIL-STD 704/1275 transients or surges the unit will shut down itself when input voltage rise above 50V and automatically recover when it drops down below 48V. For application where it require to have continuous work during the 80V/100V transient, a different configuration is optional, contact Factory for more information 2.1 Low Line Turn-on and Turn-off Limits To avoid Turn-on and Turn-off glitch the unit have about 3.5V Hysteresis. The Turn-on threshold is under 20V and turnoff under 18V. Those limits can be adjusted, contact Factory for more information. 3 Output Power The basic configuration of the M4065 can support up to 600W with the standard configuration of power per output. The Unit can support output power higher than 600W under limitation and derating, Contact Factory for more details Total Power Output 12V/30A 5V/30A 3.3V/20A 3.3VAux/5A 12VAux/1A (-)12VAux/1A 600W 30A 30A 20A 5A 1A 1A Up to 650W 35A 35A 25A 5A 1.5A 1.5A Table 4: M4065/A/B Max current per output (contact Factory) Milpower Source, Inc.

12 3.1 current sharing Current sharing give the option to draw more current from the main Outputs: VS1 12V/60A VS2 5V/60A VS3 3.3V/40A Normally the current share will be ±10% between the outputs. To obtain a good current sharing the following steps should be taken Connect hiccup pins of desired outputs to guarantee simultaneously Turn-on of paralleled outputs. Connect Sense Line of both outputs to the same point. Make sure Power trace are as identical as possible for both current sharing outputs. 1 Units efficiency (Typical results at room temperature) Input Voltage Total Power Efficiency 28V 170W 88.0% 28V 200W 87.6% 28V 600W 86.1% Milpower Source, Inc.
