HB41 Series of Half-Brick
[Type text]
[Type text]
Up to 150 Watts DC-DC Converter
[Type text]
Operating Temperature Range
This HB series of converters is rated to operate over a wide case
temperature range of -40°C to +100°C. Consideration must be given
to the de-rating curves when ascertaining maximum power that can
be drawn from the converter. The maximum power drawn from half
brick models is influenced by usual factors, such as:
•
Input voltage range
•
Output load current
•
Forced air or natural convection
Recommended Layout, PCB Footprint and
Soldering Information
The user must ensure that other components and metal in the vicinity
of the converter meet the spacing requirements to which the system
is approved. Low resistance and low inductance PCB layout should be
used where possible. Proper attention must also be given to low
impedance tracks between power module, input and output grounds.
The recommended footprints and soldering profiles are shown in the
next two figures.

Output Voltage Adjustment
Temperature (°C)
The output voltage for this HB series of 12, 15, 24, 28 and 48 Volts
models is adjustable within the range of +10% to –10%. For the 28
Volts output, it is only adjustable for -10% to 0 for inputs of 9 to 13
volts
Over Current Protection
The converter is protected against over current or short circuit
conditions. At the instance of current-limit inception, the module
enters a hiccup mode of operation, whereby it shuts down and
automatically attempts to restart. While the fault condition exists, the
module will remain in this hiccup mode, and can remain in this mode
until the fault is cleared. The unit operates normally once the output
current is reduced back into its specified range.
Output over Voltage Protection
The output overvoltage protection consists of an internal circuit that
limits the output voltage. The converter is protected against output
over voltage conditions. When the output voltage is higher than the
specified range, the module enters a hiccup mode of operation. The
operation is identical with over current protection

5. Cooling Ramp rate: -10.0
℃/Sec
(From 260℃ to 150℃)
Remote On/Off
The On/Off input pin permits the user to turn the power module on or
off via a system signal. Two remote on/off options are available.
Positive logic turns the module on during a logic high voltage on the
on/off pin, and off during a logic low. Negative logic remote on/off
turns the module off during a logic high and on during a logic low. The
on/off pin is internally pulled up through a resistor. A properly de-
bounced mechanical switch, open collector transistor, or FET can be
used to drive the input of the On/Off pin. If not using the remote on/off
feature: For positive logic, leave the On/Off pin open. For negative
logic, short the on/off pin to Vin(-).
Convection Requirements for Cooling
To predict the approximate cooling needed for the half brick module,
refer to the power de-rating curves in the next section These de-rating
curves are approximations of the ambient temperatures and airflows
required to keep the power module temperature below its maximum
rating. Once the module is assembled in the actual system, the
module’s temperature should be monitored to ensure it does not
exceed 100°C as being measured at the center of the top of the case
(thus verifying proper cooling).
UVLO (Under Voltage Lock Out)
Input under voltage lockout is standard with this converter. At input
voltages below the input under voltage lockout limit, the module
operation is disabled
.
Over Temperature Protection
These modules have an over temperature protection circuit to
safeguard against thermal damage. When the case temperature rises
above over temperature shutdown threshold, the converter will shut
down to protect it from overheating. The module will automatically
restart after it cools down.
Thermal Considerations
The power module operates in a variety of thermal environments;
however, sufficient cooling should be provided to help ensure reliable
operation of the unit. Heat is removed by conduction, convection, and
radiation to the surrounding environment. The test data is presented
in the next section. The power output of the module should not be
allowed to exceed rated power (V
o_set
x I
o_max
).
