A highly inductive source can affect the stability of the module. An input capacitance must be placed close to the modules input pins to filter ripple current and ensure module stability in the presence of inductive traces that supply the input voltage to the module.

FEATURES DESCRIPTIONS Safety Considerations Remote On/Off For safety-agency approval the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standards. The DCS series power modules have an On/Off pin for remote On/Off operation. Both positive and negative On/Off logic options are available in the DCS series power modules. For the converter output to be considered meeting the requirements of safety extra-low voltage (SELV), the input must meet SELV requirements. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. The input to these units is to be provided with a maximum 10A fuse in the ungrounded lead. Input Under voltage Lockout At input voltages below the input under voltage lockout limit, the module operation is disabled. The module will begin to operate at an input voltage above the under voltage lockout turn-on threshold. For positive logic module, connect an open collector (NPN) transistor or open drain (N channel) MOSFET between the On/Off pin and the GND pin (see figure32). Positive logic On/Off signal turns the module ON during the logic high and turns the module OFF during the logic low. When the positive On/Off function is not used, leave the pin floating or tie to Vin (module will be On). For negative logic module, the On/Off pin is pulled high with an external pull-up 5kΩ resistor (see figure 33). Negative logic On/Off signal turns the module OFF during logic high and turns the module ON during logic low. If the negative On/Off function is not used, leave the pin floating or tie to GND. (module will be on) Vo V in Over-Current Protection I O N /O F F To provide protection in an output over load fault condition, the unit is equipped with internal over-current protection. When the over-current protection is triggered, the unit enters hiccup mode. The units operate normally once the fault condition is removed.

In the event of an open remote sense line, the module shall maintain local sense regulation through an internal resistor. The module shall correct for a total of 0.5V of loss. The remote sense line impedance shall be < 10. Distribution Losses Distribution Losses Vo Vin Rtrim GND Figure 35: Circuit configuration for programming output voltage using an external resistor Table 1 provides Rtrim values required for some common output voltages, By using a 0.5% tolerance trim resistor, set point tolerance of ±1.5% can be achieved as specified in the electrical specification. Sense RL GND Distribution FigureLosses 34: Effective Distribution Losses circuit configuration for remote sense operation Output Voltage Programming The output voltage of the DCS can be programmed to any voltage between 0.59Vdc and 5.0Vdc by connecting one resistor (shown as Rtrim in Figure 35) between the TRIM and GND pins of the module. Without this external resistor, the output voltage of the module is 0.59 Vdc. To calculate the value of the resistor Rtrim for a particular output voltage Vo, please use the following equation: 5.91 Rtrim K Vo 0.591 Rtrim is the external resistor in kΩ Vo is the desired output voltage. For example, to program the output voltage of the DNS module to 5.0Vdc, Rtrim is calculated as follows: Table 1 Vo(V) Rtrim(KΩ) 0.590 Open 0.600 656.700 1.000 14.450 1.200 9.704 1.500 6.502 1.800 4.888 2.500 3.096 3.300 2.182 5.000 1.340 Certain restrictions apply on the output voltage set point depending on the input voltage. These are shown in the Output Voltage vs. Input Voltage Set Point Area plot in Figure 36. The Upper Limit curve shows that for output voltages of 0.9V and lower, the input voltage must be lower than the maximum of 14V. The Lower Limit curve shows that for output voltages of 3.8V and higher, the input voltage needs to be larger than the minimum of 4.5V. 5.91 Rtrim K 1.34 K 5.0 0.591 Figure 36: Output Voltage vs. Input Voltage Set Point Area plot showing limits where the output voltage can be set for different input voltages. DS_DCS12S0A0S06NFA_12072012 12 FEATURE DESCRIPTIONS (CON.) Voltage Margining Output voltage margining can be implemented in the DCS modules by connecting a resistor, R margin-up, from the Trim pin to the ground pin for margining-up the output voltage and by connecting a resistor, R margin-down, from the Trim pin to the output pin for margining-down. Figure 37 shows the circuit configuration for output voltage margining. If unused, leave the trim pin unconnected. A calculation tool is available from the evaluation procedure which computes the values of Rmargin-up and Rmargin-down for a specific output voltage and margin percentage. Vin Vo Rmargin-down Q1 On/Off Trim Rmargin-up Rtrim Q2 GND Figure 37: Circuit configuration for output voltage margining Output Voltage Sequencing When an analog voltage is applied to the SEQ pin, the output voltage tracks this voltage until the output reaches the set-point voltage. The final value of the SEQ voltage must be set higher than the set-point voltage of the module. The output voltage follows the voltage on the SEQ pin on a one-to-one basis. By connecting multiple modules together, multiple modules can track their output voltages to the voltage applied on the SEQ pin. For proper voltage sequencing, first, input voltage is applied to the module. The On/Off pin of the module is left unconnected (or tied to GND for negative logic modules or tied to VIN for positive logic modules) so that the module is ON by default. After applying input voltage to the module, a minimum 10msec delay is required before applying voltage on the SEQ pin. This delay gives the module enough time to complete its internal power-up soft-start cycle. During the delay time, the SEQ pin should be held close to ground (nominally 50mV ± 20 mV). This is required to keep the internal op-amp out of saturation thus preventing output overshoot during the start of the sequencing ramp. By selecting resistor R1 (see Figure. 39) according to the following equation 24950 R1 Vin 0.05 The DCS 12V 6A modules include 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, either tie the SEQ pin to VIN or leave it unconnected. Figure 38: Sequential Start-up The voltage at the sequencing pin will be 50mV when the sequencing signal is at zero. DS_DCS12S0A0S06NFA_12072012 13 FEATURE DESCRIPTIONS (CON.) Power Good The DCS modules provide a Power Good (PGOOD) After the 10msec delay, an analog voltage is applied to signal that is implemented with an open-drain output to the SEQ pin and the output voltage of the module will indicate that the output voltage is within the regulation track this voltage on a one-to-one volt bases until the limits of the power module. The PGOOD signal will be output reaches the set-point voltage. To initiate simultaneous shutdown of the modules, the SEQ pin voltage is lowered in a controlled manner. The output de-asserted to a low state if any condition such as over temperature, over current or loss of regulation occurs that would result in the output voltage going ±10% outside the set point value. The PGOOD terminal should be voltage of the modules tracks the voltages below their connected through a pull up resistor (suggested value set-point voltages on a one-to-one basis. A valid input 100KΩ) to a source of 5VDC or lower. voltage must be maintained until the tracking and output voltages reach ground potential. When using the EZ-SEQUENCETM feature to control Monotonic Start-up and Shutdown start-up of the module, pre-bias immunity during startup is disabled. The pre-bias immunity feature of the module relies on the module being in the diode-mode during The DCS 6A modules have monotonic start-up and shutdown behavior for any combination of rated input voltage, output current and operating temperature range. start-up. When using the EZ-SEQUENCETM feature, modules goes through an internal set-up time of 10msec, and will be in synchronous rectification mode when the voltage at the SEQ pin is applied. This will result in the module sinking current if a pre-bias voltage is present at the output of the module. Figure 39: Circuit showing connection of the sequencing signal to the SEQ pin. DS_DCS12S0A0S06NFA_12072012 14 THERMAL CONSIDERATIONS THERMAL CURVES Thermal management is an important part of the system design. To ensure proper, reliable operation, sufficient cooling of the power module is needed over the entire temperature range of the module. Convection cooling is usually the dominant mode of heat transfer. Hence, the choice of equipment to characterize the thermal performance of the power module is a wind tunnel. Thermal Testing Setup Delta’s DC/DC power modules are characterized in heated vertical wind tunnels that simulate the thermal environments encountered in most electronics equipment. This type of equipment commonly uses vertically mounted circuit cards in cabinet racks in which the power modules are mounted.
