E 09/02/14 Page 15 Technical Specification IQ4HxxxFTXxxx Application Section CONTROL FEATURES BASIC OPERATION AND 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. Both the first stage and the second stage switch at a fixed frequency for predictable EMI performance. The switching frequency of second stage is half of the swithcing frequency of first stage and locked in phase. 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 converter 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. This series of converters use the industry standard footprint and pin-out configuration. On when switch is open 5V VIN (+) +ON/OFF -ON/OFF VOUT (+) SENSE (+) ON/OFF(+) and ON/OFF(-) (Pin 3 and 4) - Remote ON/OFF: The ON/OFF inputs, Pins 3 and 4, permits the user to turn the converter on or off. These two inputs are fully isolated from both the input and the output side of the power converter, allowing the user the option to manage the converter from the input or the output end. The user’s on/off control signal is applied between the ON/OFF(+) pin and the ON/OFF(-) pins. Figure A details two possible circuits for driving the ON/OFF pin. Figure B is a detailed look of the internal ON/OFF circuitry. REMOTE SENSE(+) and SENSE(-) (Pins 11 and 12): The SENSE inputs correct for voltage drops along the conductors that connect the converter’s output pins to the load. Pin 11 should be connected to Vout(+) and Pin 12 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 11 and 12 must be connected regulation of the output voltage. If these are not made, the converter will deliver voltage that is slightly higher than its for proper connections an output set value. The voltage at the output terminals of the module will be trimmed up by the control circuit to compensate for voltage drops between the output pins of the module and the remote sense point. Note that the over-voltage protection (OVP) circuit senses the voltage at the output pins of the module. It is possible to inadvertently trip the OVP protection circuit if the voltage drop between the output pins and the sense point becomes too large. Hence, the remote sensing feature should be used only to compensate for small values of voltage drops to avoid triggering OVP due to a line or load transient.

E 09/02/14 Page 16 Technical Specification IQ4HxxxFTXxxx Application Section OUTPUT VOLTAGE TRIM (Pin 10): 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 10 and Pin 12 (SENSE(-) ). For a desired decrease of the nominal output voltage, the value of the resistor should be Rtrim-down = ( 90.9 Δ% ) - 0.909 (kΩ) where Δ% = | Vnominal – Vdesired Vnominal | x 100% To increase the output voltage, the user should connect a resistor between Pin 10 (TRIM) and Pin 11 (SENSE(+) ). For a desired increase of the nominal output voltage, the value of the resistor should be: Rtrim-up = ( 1.0VOUT x (100+Δ%) 1.225Δ% - 90.9 Δ% - 0.909 ) (kΩ) where Vout = Nominal Output Voltage Trim graphs(Fig.3, Fig4 and Fig5) show the relationship between the trim resistor value and Rtrim-up and Rtrimdown, 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 overvoltage 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 bypassed 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.Note that if the unit is started at no load the output voltage may, under some conditions, regulate above its rated value. This condition will be corrected once the load is increased above 1%, and it will stay corrected even if the load is lowered to zero. Product # IQ4HxxxFTXxxx Phone 1-888-567-9596 Protection Features Input Under-Voltage Lockout: 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” available 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 (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. Also see Figure E. Output Current Limit: The output current 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 Current-Limit Shutdown Voltage, the converter turns off. The converter then enters a “auto-restart” mode where it repeatedly turns on and off at a 2.5 Hz (nominal) frequency until the overload 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 400 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 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. www.synqor.com Doc.# 005-0005855 Rev.

E 09/02/14 Page 18 Technical Specification IQ4HxxxFTXxxx Application Section Startup Inhibit Period: The Startup Inhibit Period ensures that the converter will remain off for approximately 400 ms when it is shut down for any reason. For example, when an output short is present the module will shutdown, remain off for the startup inhibit period, and then attempt to restart. This results in a 2.5Hz auto restart mode of operation which prevents the converter from overheating. In all, there are seven ways that the converter 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 90 ºC. Refer to the thermal derating curve, Figure 5, to see the available output current at baseplate temperatures below 90 ºC. • • • • • • • 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 base-plate and the ambient air for a given airflow rate. This information is usually available from the heatsink vendor. The following formula can then be used to determine the maximum power the converter can dissipate for a given thermal condition: Input Under-Voltage Lockout Input Over-Voltage Lockout Output Over-Voltage Protection Over Temperature Shutdown Current Limit Short Circuit Protection Turned off by the ON/OFF input Figure E shows three turn-on scenarios, where a Startup Inhibit Period is initiated at t0, t1, and t2: 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. Pdiss max = TB - T A RTHBA This value of power dissipation can then be used in conjunction with the data shown in Figure 3 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.

E 09/02/14 Page 19 Technical Specification IQ4HxxxFTXxxx Application Section Full-Featured Application Notes This section provides some basic application information for the full-feature version of the InQor series converter. All units in this product family include back-drive protection to simplify the use of multiple converters in a parallel or sequencing application. However, any voltage applied to the output of the converter should be kept below the rated output voltage of the converter. In addition to back-drive protection, these units include the following features (pins): I Share (pin 9)-Active Current Share: Some applications benefit from connecting the outputs of multiple converters in parallel. Typical applications include systems that require power levels higher than the rated power of one converter, or systems that require N+1(less than 30) redundancy for increased reliability and availability. The active current share feature of the IQ4H Full Brick is a secondary side referenced circuit that ensures that modules configured to operate in parallel will share load current to a significant degree (±5% typical at full rated current). This feature is implemented by directly connecting the I share pins and the Start Sync pins of multiple units together. Note also that it is important to connect the SENSE(+) and SENSE(-) pins of each of the parallel modules in the same physical location to ensure the most accurate level of current sharing. The voltage at the I Share pin will range from approximately 1volt (at no load) to 2.2 volts (at full rated current), referenced to the secondary-side ground, VSENSE(-). For best performance in current shared mode,the following connections must be implemented: • I share pins of multiple units must be connected together. • Start Sync pins of multiple units must be connected together (see details below) • SENSE(+) and SENSE(-) pins of each module must be tied together at the same physical location, preferably at the end of power out cable or trace. Start Sync (pin 8) - Start Synchronization:The Start Synchronization feature is a secondary side referenced circuit that will allow a more consistent start-up sequence when the output of multiple modules are connected in parallel. To operate this feature, connect together the StartSync pins of multiple current-sharing units. This will permit immediate start-up with loads greater than the current limit of a single unit. Without this connection, any set of converters attempting to asynchronously start (or re-start) with a load greater than the current limit of a single unit will go into an auto-restart mode of operation that will continue until one converter attempts a start at the same time as the minimum number of additional units necessary to sustain the load condition. For example, three 50 amp units starting into a 90 amp load would require two units to simultaneously attempt a start. The Start Sync connection synchronizes these starting attempts and provides a more consistent and reliable start-up sequence. For details about the auto-restart mode or repeated startup attempts, please see the “Startup Inhibit Period” note in the Technical Specification. SyncIn (pin 1) – External Clock Synchronization: The Clock Synchronization is a primary side referenced feature which allows the user to control the EMI signature and synchronize sensitive circuitry to quiet periods in the converter operation. With this option, the converter can be synchronized to an external clock signal whose frequency is within the limits specified in the IQ4H-FT Family Electrical Characteristics Table. Note that increasing the converter’s frequency will tend to reduce efficiency. The Clock Synchronization feature allows the user the following choices: • Change the switching frequency of the converter from the factory pre-set value to a value in the specified range. • Synchronize the switching of all converters in a current shared mode to a common external frequency. • Improve susceptibility of an adjacent sensitive circuit by moving the converter frequency away from its most SyncOut (pin2) - Synchronization Output: The sensitive frequency. All the above are also effective means Synchronization Output is a primary side referenced of designing and managing EMI filtering to comply with the feature which provides the ability for a user to access a specified EMC standards. waveform switching synchronously with the pulse width modulator (pwm) clock of the module. The SyncOut signal • All synchronization signals (including an external clock) of one module can be used as the input to multiple other should be referenced to the negative terminal of input modules, or modules can be “daisy chained” with the voltage, Vin(-).
