A 02/06/14 Page 7 Input: 330-365V Output: 11V Current: 60A Package: EXT-Eighth Brick Applications Section BASIC OPERATION AND FEATURES CONTROL FEATURES With voltages dropping and currents rising, the economics of an Intermediate Bus Architecture (IBA) are becoming more attractive, especially in systems requiring multiple low voltages. IBA systems separate the role of isolation and voltage scaling from regulation and sensing. The BusQor series bus converter provides isolation and an unregulated voltage step down in one compact module, leaving regulation to simpler, less expensive non-isolated converters. 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(-). In the negative logic version, the ON/OFF signal is active low (meaning that a low turns the converter on). Figure B is a detailed look of the internal ON/OFF circuitry. In Figure A below, the BusQor module provides the isolation stage of the IBA system. The isolated bus then distributes power to the non-isolated buck regulators to generate the required voltage levels at the points of load. In this case, the bucks are represented with SynQor’s NiQor series of nonisolated DC-DC converters. In many applications requiring multiple low voltage outputs, significant savings can be achieved in board space and overall system costs When designing an IBA system with bus converters, the designer can select from a variety of bus voltages. While there is no universally ideal bus voltage, most designs employ one of the following: 12V, 11V, 9.6V, 7.5V, 5V, or 3.3V. Higher bus voltages can lead to lower efficiency for the buck regulators but are more efficient for the bus converter and provide lower board level distribution current. Lower bus voltages offer the opposite trade offs. 5V 82.5K PIN2 PIN3 ON/OFF 10K TO ENABLE CIRCUITRY IN RTN Figure B: Internal ON/OFF pin circuitry SynQor’s BusQor modules act as a true dc transformer. The output voltage is proportional to the input voltage, with a specified “turns ratio” or voltage ratio, plus minor drop from the internal resistive losses in the module. When used in IBA systems, the output variation of the BusQor must be in accordance with the input voltage range of the non-isolated converters being employed. The BusQor architecture is very scalable, meaning multiple bus converters can be connected directly in parallel to allow current sharing for higher power applications. 3.3V 48Vdc Front End 352Vdc 330-365V BusQor Converter 2.5V 11.0Vdc 1.8V 1.5V 0.9V Typical User Board NiQor Converters Loads Figure A: Example of Intermediate Bus Architecture using BusQor bus converter and NiQor non-isolated converters Product # BQ35211EEC60 Phone 1-888-567-9596 www.synqor.com Doc.# 005-0006545 Rev. A 02/06/14 Page 8 Input: 330-365V Output: 11V Current: 60A Package: EXT-Eighth Brick Applications Section 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”. 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 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 of the BusQor module is electronically protected against output overloads. When an overload current greater than the “DC Current-Limit Inception” specification is drawn from the output, the output shuts down to zero volt in a period of 1ms typical (see Figure C). The shutdown period lasts for a typical period of 200ms (Figure D) after which the BusQor tries to power up again (10ms). If the overload persists, the output voltage will go through repeated cycles of shutdown and restart with a duty cycle of 4.8% (On) and 95.2% (Off) respectively. The BusQor module returns (auto resetting) to normal operation once the overload is removed. The BusQor is designed to survive in this mode indefinitely without damage and without human intervention. Output Current 68A 60A Output Voltage 80 A peak Output Voltage <11V 0V Time 210ms 10ms Figure D: Output Short Circuit and Auto-Resetting protection diagram (not to scale) Output Short Circuit Protection: When the output of the BusQor module is shorted, a peak current of typically 80 A will flow into the short circuit for a period of about 1ms. The output of the BusQor will shutdown to zero for ~ 200mS (Figure D). At the end of the shutdown period the BusQor module tries to power up again. If the short circuit persists, the output voltage will go through repeated cycles of shutdown and restart with a duty cycle of 4.8% (On) and 95.2% (Off) respectively. The BusQor module returns (auto resetting) to normal operation once the short circuit is removed. The BusQor is designed to survive in this mode indefinitely without damage and without human intervention. In the Auto resetting mode, also referred to as “Hiccup” mode, the power drawn from the 352V input is about 5 Watts, most of which is dissipated into the external fault. It is important that copper traces and pads from the output circuit be designed to withstand the short term peaks, although the average current into the fault may be as low as 0.015A typical. See Figure 18 for appropriate waveform. 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. 11.0V 0V 1ms Output Current Time Figure C: Output Overload protection diagram (not to scale) Product # BQ35211EEC60 Phone 1-888-567-9596 www.synqor.com Doc.# 005-0006545 Rev.

Fall time from 11.0V to 0V is dependent on output capacitance and any parasitic trace inductance in the output load circuit. At time t3, when the On/Off pin is re-asserted (enabled), the BusQor module output begins to build up after the inhibit period of 800 ms typical has elapsed. Refer to the Control Features section of the data sheet for details on enabling and disabling methods for Bus Qor modules. 4.0% Deviation from 50/50 Sharing (%) Start-Up Inhibit Period: Figure E details the Start-Up Inhibit Period for the BusQor module. At time t0, when Vin is applied with On/Off pin asserted (enabled), the BusQor output begins to build up. Before time t1, 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 typical Startup Inhibit Period of 12ms is initiated. The output builds up to 90% of the nominal value of 11.0V in a period of 5ms typical (50 % load). 3.0% 2.0% 1.0% 0.0% -1.0% -2.0% -3.0% Module 1 -4.0% -5.0% Module 2 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 Total Load Current (A) Figure G: Typical current share performance of 2 paralleled modules Current Sharing: BusQor modules are designed to operate in parallel without the use of any external current share circuitry. A typical (recommended) circuit for paralleling two BusQor modules is shown in Figure H. An output capacitor is recommended across each module and located close to the converter for optimum filtering and noise control performance. Dedicated input inductors are recommended but are considered optional. Input capacitors must be located close to the converter module. PCB layout in the input circuit should be such that high frequency ripple currents of each module is restricted to a loop formed by the input capacitors and the input terminals of the BusQor module.
