7 / 14 page Advance Data Sheet November 17, 2011 40A Analog Mega DLynxTM: Non-isolated DC-DC Power Module 4.5 – 14.4Vdc input; 0.6Vdc to 2Vdc output; 40A output current LINEAGE POWER 7 Feature Descriptions Remote On/Off The 40A Analog Mega DLynx TM power modules feature an On/Off pin for remote On/Off operation. Two On/Off logic options are available. In the Positive Logic On/Off option, (device code suffix “4” – see Ordering Information), the module turns ON during a logic High on the On/Off pin and turns OFF during a logic Low. With the Negative Logic On/Off option, (no device code suffix, see Ordering Information), the module turns OFF during logic High and ON during logic Low. The On/Off signal should be always referenced to ground. For either On/Off logic option, leaving the On/Off pin disconnected will turn the module ON when input voltage is present. Monotonic Start-up and Shutdown The module has monotonic start-up and shutdown behavior for any combination of rated input voltage, output current and operating temperature range. Startup into Pre-biased Output The module can start into a prebiased output as long as the prebias voltage is 0.5V less than the set output voltage. Output Voltage Programming The output voltage of the module is programmable to any voltage from 0.6dc to 2Vdc by connecting a resistor between the Trim and SIG_GND pins of the module. Without an external resistor between Trim and SIG_GND pins, the output of the module will be 0.6Vdc. To calculate the value of the trim resistor, Rtrim for a desired output voltage, should be as per the following equation: () Ω − = k Vo Rtrim 6 . 0 12 Rtrim is the external resistor in kΩ Vo is the desired output voltage. Table 1 provides Rtrim values required for some common output voltages. VO(+) TRIM VS─ Rtrim LOAD VIN(+) ON/OFF VS+ SIG_GND Caution – Do not connect SIG_GND to GND elsewhere in the layout Figure 3.

The voltage between the SENSE pin and VOUT pin should not exceed 0.5V. Voltage Margining Output voltage margining can be implemented in the module by connecting a resistor, Rmargin-up, from the Trim pin to the ground pin for margining-up the output voltage and by connecting a resistor, Rmargin-down, from the Trim pin to output pin for margining-down. Figure 4 shows the circuit configuration for output voltage margining Figure 4. Circuit Configuration for margining Output voltage. Output Voltage Sequencing The power module includes a sequencing feature, EZ- SEQUENCE that enables users to implement various types of output voltage sequencing in their applications. This is accomplished via an additional sequencing pin. When not using the sequencing feature, leave it unconnected. The voltage applied to the SEQ pin should be scaled down by the same ratio as used to scale the output voltage down to the reference voltage of the module. This is accomplished by an external resistive divider Vo MODULE SIG_GND Trim Q1 Rtrim Rmargin-up Q2 Rmargin-down |
