A 04/06/2016 Page 13 Technical Specification RQ18xxxHPXxx Application Section BASIC OPERATION AND FEATURES CONTROL FEATURES This converter series uses a two-stage power conversion topology. The first stage is a buck-converter that keeps the output voltage constant over variations in line, load, and temperature. The second stage uses a transformer to provide the functions of input/output isolation and voltage step-up or step-down to achieve the output voltage required. REMOTE ON/OFF (Pin 2): The ON/OFF input, Pin 2, permits the user to control when the converter is on or off. This input is referenced to the return terminal of the input bus, Vin(-). Both the first stage and the second stage switch at a fixed frequency for predictable EMI performance. Rectification of the transformer’s output is accomplished with synchronous rectifiers. These devices, which are MOSFETs with a very low on-state resistance, dissipate far less energy than Schottky diodes. This is the primary reason that the converter has such high efficiency, even at very low output voltages and very high output currents. These converters are offered totally encased to withstand harsh environments and thermally demanding applications. Conductive cooling design can be used with heat sink or cold plate cooling systems. Full power is available with baseplate temperature up to 100°C. This series of converters use the industry standard footprint and pin-out configuration. ON/OFF The ON/OFF signal is active low (meaning that a low voltage turns the converter on). Figure A details four possible circuits for driving the ON/OFF pin. REMOTE SENSE(±) (Pins 7 and 5): The SENSE(±) inputs correct for voltage drops along the conductors that connect the converter’s output pins to the load. Pin 7 should be connected to Vout(+) and Pin 5 should be connected to Vout(-) at the point on the board where regulation is desired. A remote connection at the load can adjust for a voltage drop only as large as that specified in this datasheet, that is [Vout(+) - Vout(-)] – [Vsense(+) - Vsense(-)] < Sense Range % x Vout Pins 7 and 5 must be connected for proper regulation of the output voltage. If these connections are not made, the converter will deliver an output voltage that is slightly higher than its specified value. Note: The output over-voltage protection circuit senses the voltage across the output (pins 8 and 4) to determine when it should trigger, not the voltage across the converter’s sense leads (pins 7 and 5). Therefore, the resistive drop on the board should be small enough so that output OVP does not trigger, even during load transients.

A 04/06/2016 Page 14 Technical Specification Application Section OUTPUT VOLTAGE TRIM (Pin 6): The TRIM input permits the user to adjust the output voltage across the sense leads up or down according to the trim range specifications. To decrease the output voltage, the user should connect a resistor between Pin 6 and Pin 5 (SENSE(-) input). For a desired decrease of the nominal output voltage, the value of the resistor should be: Rtrim-down = ( Δ% = | ) - 10.22 [kΩ] 511 Δ% where Vnominal – Vdesired Vnominal | x 100% To increase the output voltage, the user should connect a resistor between Pin 6 and Pin 7 (SENSE(+) input). For a desired increase of the nominal output voltage, the value of the resistor should be: Rtrim-up = ( 5.11VOUT x (100+Δ%) 1.225Δ% - 511 Δ% - 10.22 ) [kΩ] Trim graphs show the relationship between the trim resistor value and Rtrim-up and Rtrim-down, showing the total range the output voltage can be trimmed up or down. Note: The TRIM feature does not affect the voltage at which the output over-voltage protection circuit is triggered. Trimming the output voltage too high may cause the over-voltage protection circuit to engage, particularly during transients. It is not necessary for the user to add capacitance at the Trim pin. The node is internally filtered to eliminate noise. Total DC Variation of Vout: For the converter to meet its full specifications, the maximum variation of the DC value of Vout, due to both trimming and remote load voltage drops, should not be greater than that specified for the output voltage trim range. RQ18xxxHPXxx Protection Features Input Under-Voltage Lockout: The converter is designed to turn off when the input voltage is too low, helping to avoid an input system instability problem, which is described in more detail in the application note titled “Input System Instability” on www.synqor.com. The lockout circuitry is a comparator with DC hysteresis. When the input voltage is rising, it must exceed the typical “Turn-On Voltage Threshold” value* before the converter will turn on. Once the converter is on, the input voltage must fall below the typical Turn-Off Voltage Threshold value before the converter will turn off. Output Current Limit: The maximum current limit remains constant as the output voltage drops. However, once the impedance of the load across the output is small enough to make the output voltage drop below the specified Output DC CurrentLimit Shutdown Voltage, the converter turns off. The converter then enters a “hiccup mode” where it repeatedly turns on and off at a 5 Hz (nominal) frequency with a 5% duty cycle until the short circuit condition is removed. This prevents excessive heating of the converter or the load board. Output Over-Voltage Limit: If the voltage across the output pins exceeds the Output Over-Voltage Protection threshold, the converter will immediately stop switching. This prevents damage to the load circuit due to 1) excessive series resistance in output current path from converter output pins to sense point, 2) a release of a short-circuit condition, or 3) a release of a current limit condition. Load capacitance determines exactly how high the output voltage will rise in response to these conditions. After 200 ms the converter will automatically restart. Over-Temperature Shutdown: A temperature sensor on the converter senses the average temperature of the module. The thermal shutdown circuit is designed to turn the converter off when the temperature at the sensed location reaches the “OverTemperature Shutdown” value*. It will allow the converter to turn on again when the temperature of the sensed location falls by the amount of the “Over-Temperature Shutdown Restart Hysteresis” value*. Transient and Surge Protection: The wide input range of the RailQor line of converters covers all transient requirements of EN 50155. For short duration transients and surges found in other standards (such as RIA 12) that exceed the maximum input voltage rating of the converter, SynQor has provided a design guide for a transient suppression circuit.

A 04/06/2016 Page 16 Technical Specification RQ18xxxHPXxx Application Section Startup Inhibit Period: The Startup Inhibit Period ensures that the converter will remain off for approximately 200 ms when it is shut down for any reason. When an output short is present, this generates a 5 Hz “hiccup mode,” which prevents the converter from overheating. In all, there are six ways that the converter can be shut down, initiating a Startup Inhibit Period: • • • • • • When the ON/OFF pin goes high after t2, the Startup Inhibit Period has elapsed, and the output turns on within the typical Turn-On Time. Thermal Considerations: The maximum operating base-plate temperature, TB, is 100 ºC. As long as the user’s thermal system keeps TB < 100 ºC, the converter can deliver its full rated power. Input Under-Voltage Lockout Output Over-Voltage Protection Over Temperature Shutdown Current Limit Short Circuit Protection Turned off by the ON/OFF input A power derating curve can be calculated for any heatsink that is attached to the base-plate of the converter. It is only necessary to determine the thermal resistance, RTH-BA, of the chosen heatsink between the base-plate and the ambient air for a given airflow rate. This information is usually available from the heatsink vendor. The following formula can the be used to determine the maximum power the converter can dissipate for a given thermal condition if its base-plate is to be no higher than 100 ºC. Figure E shows three turn-on scenarios, where a Startup Inhibit Period is initiated at t0, t1, and t2: Pdiss max = 100 ºC - TA RTH-BA Before time t0, when the input voltage is below the UVL threshold, the unit is disabled by the Input Under-Voltage Lockout feature. When the input voltage rises above the UVL threshold, the Input Under-Voltage Lockout is released, and a Startup Inhibit Period is initiated. At the end of this delay, the ON/OFF pin is evaluated, and since it is active, the unit turns on. This value of power dissipation can then be used in conjunction with the data shown in Figure 2 to determine the maximum load current (and power) that the converter can deliver in the given thermal condition. At time t1, the unit is disabled by the ON/OFF pin, and it cannot be enabled again until the Startup Inhibit Period has elapsed. For convenience, power derating curves for an encased converter without a heatsink are provided for each output voltage.

A 04/06/2016 Page 17 Technical Specification Application Section Designing for Maximizing Available Power: RailQor products have been designed for full power operation in demanding thermal environments. However, there are techniques that can be applied external to the converter to ensure the best possible thermal performance. These include correctly applying a heatsink to the baseplate of the converter and maximizing the heat transferred through the pins. The following discussions are only guidelines and may not be necessary depending on the application Optimal Heatsink Application: There are two key components to maximizing the thermal dissipation when using a heatsink. One is minimizing the thermal resistance between the converter and the heatsink itself. There are imperfections between the mating surfaces that reduce contact area between the two. A suitable thermally conductive interface material should be used to maintain a good thermal connection. A commonly used example is thermal grease. When utilizing the threaded inserts on the baseplate of a SynQor converter, care must be taken not to exceed the torque or screw depth guidelines found in the mechanical diagram. Two, airflow must be directed to pass between the fins of the heatsink to maximize the surface area for heat removal. Heatsinks are often available with both transverse and longitudinal fin direction to allow system flexibility. Care should be taken to avoid large external components surrounding the converter from blocking airflow. Figure F: Example of properly soldered pin joint Product # RQ18xxxHPXxx Phone 1-888-567-9596 RQ18xxxHPXxx Layout Considerations: Significant performance improvement can be made by designing a printed circuit board to properly sink heat away from the converter through its pins. The first step is to ensure a correctly formed solder joint at each pin. A smooth fillet and complete barrel fill should be observed at the boundary of pin and mounting hole to ensure maximum heat conduction from pin to board (Figure F). It is worth noting here that encased SynQor products are not compatible with reflow processes as it may disrupt the placement of internal components. The board itself should also have as many layers and as high of copper weight as is practical for the application. Large ground and power planes are best as the most heat will be conducted through the large power pins of the converter on both input and output sides. The heat must also have a path to conduct from the copper planes of the board to the outside environment. The typical FR4 material used in construction of a printed circuit board is greater than 1000 times less thermally conductive than copper and will act as an insulator between each copper plane. To mitigate this, generous use of thermal vias is recommended in the board area surrounding and below the converter. A proper density of vias allows heat to conduct from the board to the air while maintaining a large amount of copper area to conduct to the vias. For reference, boards used in SynQor thermal testing are 6 layer, 2 oz. copper boards with 50 mil diameter thermal vias at a density of 36/in2 (Figure G).
