A04/30/2015 Page 7 MCOTS-N-12-Q3P1N-QT Quad Output Quarter-Brick BASIC OPERATION AND FEATURES The MCOTS-N QUAD Output non-isolated dc-dc converter generates three positive output voltages and one negative output voltage. The output voltage is kept constant over variations in line, load, and temperature. The modules employ synchronous rectification for very high efficiency. The converter runs at a fixed frequency with a predictable EMI performance. These converters are offered totally encased to withstand harsh environments and thermally demanding applications. Dissipation throughout the converter is so low that it does not require a heatsink for operation in many applications; however, adding a heatsink provides improved thermal derating performance in extreme situations. CONTROL FEATURES REMOTE ON/OFF: The ON/OFF input permits the user to control when the converter is on or off. The ON/OFF signal is active low (meaning that a low turns the converter on). Figure A details four possible circuits for driving the ON/OFF pin. ON/OFF ON/OFF OUTPUT VOLTAGE TRIM: The TRIM input permits the user to adjust the output voltage according to the trim range specifications by using an external resistor. For positive outputs: To increase the output voltage from the nominal setpoint of 0.8V using an external resistor, connect the resistor Rtrim_pos between the TRIM and the Ground pin. For a desired increase of the nominal output voltage, the value of the resistor should be: Rtrim_pos = Remote Enable Circuit Open Collector Enable Circuit ON/OFF Vin(_) Vin(_) 1200 Rtrim_pos (Ω) + 100 (V) -100 Vneg-122.5 Vneg + 13.475 (kΩ) 13.475Rtrim_neg (kΩ) + 122.5 Rtrim_neg + 100 (V) where Vneg is a negative number Negative Logic (Permanently Enabled) 5V ON/OFF TTL/ CMOS _ 100 (Ω) For negative output: To increase the output voltage from the nominal setpoint of -13.475V using an external resistor, connect the resistor Rtrim_neg between the TRIM and the Ground pin. For a desired increase of the nominal output voltage, the value of the resistor should be: Rtrim_neg = Vin(_) VPOS - 0.8 Vpos = 0.8 + Vneg = Vin(_) 1200 To maintain the accuracy of the output voltage over load current, it is vital that any trim resistor be terminated directly to the converter’s Ground pin, not at the connection to the load. We do not recommend bypassing the trim pin directly to ground with a capacitor. The voltage gain from the trim pin to output is rather large, 15:1. Ground bounce through a bypass capacitor could introduce significant noise to the converter’s control circuit. Direct Logic Drive Figure A: Various circuits for driving the ON/OFF pin. REMOTE SENSE+: The SENSE+ inputs are available for main positive outputs and they correct for voltage drops along the conductors that connect the converter’s output pins to the load. The SENSE+ pins should be connected to respective VOUT+ at the point on the board where regulation is desired. SENSE+ pins 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.

A04/30/2015 Page 8 MCOTS-N-12-Q3P1N-QT Quad Output Quarter-Brick PROTECTION FEATURES APPLICATION CONSIDERATIONS Input Under-Voltage Lockout: For positive outputs the converter is designed to turn off when the input voltage is too low, helping avoid an input system instability problem, described in more detail in the application note titled “Input System Instability”. 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 (listed on the specification page) 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. Input Filtering/Capacitance/Damping: The filter circuit of Figure B is often added to the converter’s input to prevent switching noise from reaching the input voltage bus. Output Current Limiting: To provide protection in an output over load fault condition, the unit is equipped with internal over-current protection. For positive outputs, when the overcurrent protection is triggered, the unit enters hiccup mode. The units operate normally once the fault condition is removed. For negative output, the output voltage decreases to support load current. Figure B: Converter with Input Filter. Note: The maximum load current negative output can deliver varies with input and output voltage. The nominal max load current, Imax_nom, is 1A, when Vin ≥ |Vneg|. When Vin < |Vneg|, the maximum load current is: 2Vin Imax= Imax_nom X Vin +|Vneg| Internal Over-Voltage Protection: To fully protect from excessive output voltage, this series contains an Output OverVoltage Shutdown circuitry. The OVP function is for main positive outputs only. This OVP is independent of the trimmed setpoint. As such, the converter’s load is protected from faults in the external trim circuitry (such as a trim pin shorted to ground). Since the setpoint of this OVP does not track trim, it is set at 6.0V. For more detailed information contact SynQor technical support. Over-Temperature Shutdown: Temperature sensors on the converters sense 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 Over-Temperature 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. With Lin of 1μH, Cd should be 100-200μF and Rd should be 0.1‑0.2Ω, in most applications. For more information on designing the input filter and choosing proper values, contact SynQor technical support. Adding significant external pure ceramic capacitance directly across the converter’s input pins is not recommended. Parasitic inductance associated with the input pin geometry and PCB traces can create a high-Q C-L-C circuit with any external capacitors. Just a few nano-Henries of parasitic inductance can create a resonance (or an overtone) near the converter’s switching frequency. To avoid this high-frequency resonance, any external input filter should exhibit a net source impedance of at least 20mΩ resistive through this frequency range. This requirement is easily met with the damping elements discussed above. Adding a small amount (a few μF) of high-frequency external ceramic will not violate it. If using converters at higher powers, consider the ripple current rating of Cd. Contact SynQor technical support for details. Output Capacitance: It is recommended to add at least 100μF of capacitance, with an ESR in the 0.1Ω range, to the output of the converters. In many applications, however, additional external output capacitance is required to reduce the response to load transients to an allowable level. For minimal overshoot upon recovery, Cd should be related to the minimum in-circuit net ESR. For more detailed derivations of these values contact SynQor technical support.

A04/30/2015 Page 9 MCOTS-N-12-Q3P1N-QT Quad Output Quarter-Brick Thermal Consideration: The maximum operating baseplate temperature, TB, is 100 ºC. Refer to the Thermal Derating Curves in the Technical Figures section to see the available output current at baseplate temperatures below 100 ºC. P max diss = TB - TA RTHBA This value of maximum power dissipation can then be used in conjunction with the data shown in the Power Dissipation Curves in the Technical Figures section to determine the maximum load current (and power) that the converter can deliver in the given thermal condition. For convenience, Thermal Derating Curves are provided in the Technical Figures section. 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, RTHBA, of the chosen heatsink between the baseplate and the ambient air for a given airflow rate. This information is usually available from the heatsink vendor. The following formula can 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.
