G 11/12/15 Page 21 Technical Specification IQ48xxxSMXxxx Application Section BASIC OPERATION AND FEATURES This converter series uses a two-stage power topology. The first stage is a buck-converter that output voltage constant over variations in line, temperature. The second stage uses a transformer the functions of input/output isolation and voltage step-down to achieve the output voltage required. conversion keeps the load, and to provide step-up or 5V 10k ON/OFF 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. 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 demanding applications. This series of converters use the industry standard footprint and pin-out configuration. TTL 1000pF Vin(-) Figure B: Internal ON/OFF pin circuitry 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 load 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(-)] < CONTROL FEATURES Sense Range % x Vout 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(-). 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. Figure B is a detailed look of the internal ON/ OFF circuitry. ON/OFF ON/OFF Sense Range % = Trim-up Range % (usually 10 %) 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.

G 11/12/15 Page 22 Technical Specification IQ48xxxSMXxxx 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 = - 10.22 (511 D% ) [kW] where D% = 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 = where ( 5.11VOUT x (100+D%) 1.225D% _ 511 _ 10.22 D% ) [kW] Vout = Nominal Output Voltage Trim graphs show the relationship between the trim resistor value 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 bypassed to eliminate noise. * For 1.2Vout unit replace 1.225 with 0.6 (see Trim Up Graph Common Figure 3). 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” on our website. The lockout circuitry is a comparator with dc hysteresis. When the input voltage is rising, it must exceed the typical TurnOn Voltage Threshold value (listed on the specifications 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. Output Current Limit: The maximum current limit remains constant as the output voltage drops. However, once the output voltage drops below the specified Output DC Current-Limit 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 overload is removed. This prevents excessive heating of the converter or the system 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 overload 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 internal converter PCB 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. 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.

G 11/12/15 Page 23 Technical Specification IQ48xxxSMXxxx Application Section APPLICATION CONSIDERATIONS Input System Instability: This condition can occur because any dc-dc converter appears incrementally as a negative resistance load. A detailed application note titled “Input System Instability” is available on the SynQor website which provides an understanding of why this instability arises, and shows the preferred solution for correcting it. The Electrical Characteristics Table indicates a “Recommended External Input Capacitance”. The value needed for that capacitance and ESR can vary based on application parameters. Input stability can be evaluated using our “Stability Calculator” tool in the Technical Support section of our website www.synqor.com.

Input Filtering and External Capacitance: Figure D provides a diagram showing the internal input filter components. This filter dramatically reduces input terminal ripple current, which otherwise could exceed the rating of an external electrolytic input capacitor. The recommended external input capacitance is specified in the Input Characteristics section on the Electrical Characteristics page. The input capacitance need not exactly match the specified value.

G 11/12/15 Page 24 Technical Specification IQ48xxxSMXxxx 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 seven ways that the converter can be shut down, initiating a Startup Inhibit Period: • InputUnder-VoltageLockout When the ON/OFF pin goes low after t2, and the Startup Inhibit Period has elapsed, and the output turns on within the typical Turn-On Time. Thermal Considerations: The maximum operating baseplate 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. A power derating curve can be calculated for any heatsink that is attached to the baseplate 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 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 if its baseplate is to be no higher than 100 ºC. • InputOver-VoltageShutdown • OutputOver-VoltageProtection • OverTemperatureShutdown • CurrentLimit(whenVoutisbelowshutdownvoltage) • ShortCircuitProtection • TurnedoffbytheON/OFFinput 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 (UVL) 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. 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. max Pdiss = 100 ºC - TA RTHBA 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. We recommend that a suitable thermal interface material such as a thermally conductive pad or grease be used to assure a good thermal interface between the base plate and the conductive cooling device.
