DC-DC Converter
The BQ35211EEC60 bus converter is a next-generation,
board-mountable, isolated, fixed switching frequency
DC-DC converter that uses synchronous rectification
to achieve extremely high conversion efficiency.
The Bus Qor series provides an isolated step down
voltage from 352V to 11V intermediate bus with no
regulation in a extended eighth-brick module. The
BQ35211EEC60 converter is ideal for creating the midbus voltage required to drive standard DC-DC nonisolated converters.

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.

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.

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.

Figure D: Output Short Circuit and Auto-Resetting protection diagram (not to

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.

APPLICATION CONSIDERATIONS

At time t2, when the On/Off pin is de-asserted (disabled), the BusQor
output instantly drops to 0V. 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.

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).

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. See
Figure H for details on PCB layout. Contact SynQor application engineering
for further assistance on PCB trace design.

The current share performance of two paralleled modules is illustrated
in the graph in Figure G. In this graph the percent deviation from ideal
sharing (50%) is plotted for each module versus the total output load
current at 352Vin.
