FEATURES
PRODUCT OVERVIEW
Up to 210 Watts total output power
The present trend in distributed power architectures (DPA) requires both high efficiency and some
regulation of the output voltage to reduce the risk
of under voltage dropout. Earlier unregulated bus
converters were simply ratiometric “DC transformers.” The fully isolated (2250Vdc) RBC series accept
a wide range 36 to 75 Volt DC input (48V nominal)
and convert it to an output of 12Vdc. This output
then drives point-of-load (PoL) converters such as
our Okami, LSN, LEN, LSM or LQN series which
feature precise load regulation. Applications include
48V-powered datacom and telecom installations,
base stations, cellular telephone repeaters and
embedded systems. Low overall height of 0.42"
(10.7 mm) fits tight card cages.

input undervoltage (UV) lockout, output current limit,
short circuit hiccup, overtemperature shutdown and
output overvoltage. Available options include positive or negative logic remote On/Off control and the
baseplate. Assembled using ISO-certified automated
surface-mount techniques, the RBC series includes
all UL and IEC emissions, safety and flammability
certifications.

allow the instantaneous input voltage to go below the minimum voltage at all
times. Even if this voltage depression is very brief, this may interfere with the
on-board controller and possibly cause a failed start.
Start-Up Considerations
Use a moderate size capacitor very close to the input terminals. You may need
two parallel capacitors. A larger electrolytic or tantalum cap supplies the surge
current and a smaller parallel low-ESR ceramic cap gives low AC impedance.
When power is first applied to the DC/DC converter, there is some risk of start
up difficulties if you do not have both low AC and DC impedance and adequate
regulation of the input source. Make sure that your source supply does not
Remember that the input current is carried both by the wiring and the ground
plane return. Make sure the ground plane uses adequate thickness copper. Run
additional bus wire if necessary.

Technical Notes
I/O Filtering and Noise Reduction
The RBC is tested and specified with external output capacitors. These
capacitors are necessary to accommodate our test equipment and may not
be required to achieve desired performance in your application. The RBC is
designed with high-quality, high-performance internal I/O caps, and will operate within spec in most applications with no additional external components.
In particular, the RBC input capacitors are specified for low ESR and are fully
rated to handle the units' input ripple currents. Similarly, the internal output
capacitors are specified for low ESR and full-range frequency response.
In critical applications, input/output ripple/noise may be further reduced using
filtering techniques, the simplest being the installation of external I/O caps.
External input capacitors serve primarily as energy-storage devices. They
minimize high-frequency variations in input voltage (usually caused by IR
drops in conductors leading to the DC/DC) as the switching converter draws
pulses of current. Input capacitors should be selected for bulk capacitance
(at appropriate frequencies), low ESR, and high rms-ripple-current ratings.
The switching nature of modern DC/DC's requires that the dc input voltage
source have low ac impedance at the frequencies of interest. Highly inductive
source impedances can greatly affect system stability. Your specific system
configuration may necessitate additional considerations.
Input Fusing
Most applications and or safety agencies require the installation of fuses at
the inputs of power conversion components. The RBC Series may have an
optional input fuse. Therefore, if input fusing is mandatory, either a normalblow or a fast-blow fuse with a value no greater than twice the maximum
input current should be installed within the ungrounded input path to the
converter.
Input Overvoltage and Reverse-Polarity Protection
The RBC does not incorporate input reverse-polarity protection. Input voltages
in excess of the specified absolute maximum ratings and input polarity reversals of longer than "instantaneous" duration can cause permanent damage to
these devices.
Start-Up Time
The VIN to VOUT Start-Up Time is the interval between the time at which a rising
input voltage crosses the lower limit of the specified input voltage range
TO
OSCILLOSCOPE
CURRENT
PROBE
VIN
LBUS
CBUS
The On/Off to VOUT Start-Up Time assumes the converter is turned off via the
On/Off Control with the nominal input voltage already applied to the converter.
The specification defines the interval between the time at which the converter
is turned on and the fully loaded output voltage enters and remains within its
specified regulation band.
Thermal Considerations and Thermal Protection
The typical output-current thermal-derating curves shown below enable
designers to determine how much current they can reliably derive from each
model of the RBC under known ambient-temperature and air-flow conditions.
Similarly, the curves indicate how much air flow is required to reliably deliver
a specific output current at known temperatures.
The highest temperatures in RBC's occur at their output inductor, whose heat
is generated primarily by I 2 R losses. The derating curves were developed
using thermocouples to monitor the inductor temperature and varying the load
to keep that temperature below +110°C under the assorted conditions of air
flow and air temperature. Once the temperature exceeds +125°C (approx.),
the thermal protection will disable the converter using the hiccup shutdown
mode.
Undervoltage Shutdown
When the input voltage falls below the undervoltage threshold, the converter
will terminate its output. However, this is not a latching shutdown mode. As
soon as the input voltage rises above the Start-Up Threshold, the converter
will restore normal operation. This small amount of hysteresis prevents most
uncommanded power cycling. Since some input sources with higher output
impedance will increase their output voltage greater than this hysteresis as
soon as the load is removed, it is possible for this undervoltage shutdown to
cycle indefinitely. To prevent this, be sure that the input supply always has
adequate voltage at full load.
Thermal Shutdown
Extended operation at excessive temperature will initiate overtemperature
shutdown triggered by a temperature sensor inside the PWM controller. This
operates similarly to overcurrent and short circuit mode. The inception point of
the overtemperature condition depends on the average power delivered, the
ambient temperature and the extent of forced cooling airflow.
Remote On/Off Control
+INPUT
+
and the fully loaded output voltage enters and remains within its specified
regulation band. Actual measured times will vary with input source impedance, external input capacitance, and the slew rate and final value of the input
voltage as it appears to the converter.
CIN
The RBC may be turned off or on using the external remote on/off control. This
terminal consists of a digital input to the internal PWM controller through a
protective resistor and diode.

CIN = 33µF, ESR < 700m7 @ 100kHz

LBUS = 12µH
The on/off input circuit should be CMOS logic referred to the –Input power
terminal however TTL or TTL-LS logic will also work or a switch to ground. If
preferred, you can even run this using a bipolar transistor in “open collector”
configuration or an “open drain” FET transistor. You may also leave this input
unconnected and the converter will run whenever input power is applied.

Both through-hole and surface mount converters are soldered down to a host
carrier board for realistic heat absorption and spreading. Both longitudinal and
transverse airflow studies are possible by rotation of this carrier board since
there are often significant differences in the heat dissipation in the two airflow
directions. The combination of adjustable airflow, adjustable ambient heat, and
adjustable Input/Output currents and voltages mean that a very wide range of
measurement conditions can be studied.
The collimator reduces the amount of turbulence adjacent to the UUT by
minimizing airflow turbulence. Such turbulence influences the effective heat
transfer characteristics and gives false readings. Excess turbulence removes
more heat from some surfaces and less heat from others, possibly causing
uneven overheating.
