POINT OF LOAD (POL) VOLTAGE REGULATOR
Description
The SBB Series point of load (POL) DC to DC voltage
regulators are high reliability hermetically sealed thick film
hybrids designed to provide a single regulated DC output
from a DC voltage source. The output power rating is 14W
to 30W depending on output voltage, with maximum current
SBB
rating of 14A. The POLs are class K qualified per MIL-PRF-38534.
These products are designed to operate continuously on

board a space craft up to the rated power output without
power de-rating for case temperature of 85°C.The POLs
are suitable for harsh radiation environments normally encountered
in the geo-synchronous orbit (GEO), medium earth orbit
(MEO), low earth orbit (LEO), deep space, and for other
challenging radiation design applications.
Output power up to 30W or 14A maximum without

High efficiency to 89%
The SBB POL is a non isolated synchronous buck regulator. It
incorporates IR HiRel’s heritage-rich components and circuit
design library for long term reliability expected of system
designs with a mission life of up to 18 years or more. The
SBB Series of POLs operate from a DC input power source
with the voltage range of 4.5V to 5.5V. It converts DC input
voltage down to a fixed and highly stable DC output. The
standard voltage outputs are 1.0V, 1.2V, 1.5V, 1.8V, 2.5V,
and 3.3V. The output is adjustable with the addition of an
external resistor. The output adjustment range is approximately
±10% of a nominal output voltage. Also included is remote
sensing capability to compensate for voltage drops in the
output lines. This feature, in combination with the output
adjustment capability, enables an output voltage of a POL to be
accurately set as needed.

(Single Output)
The product’s package footprint is less than three square
inches. The package and lid materials are cold rolled steel. The
low profile package measures 1.9"L x 1.5"W x 0.335"H, excluding
mounting tabs and input/output (I/O) pins. The ceramic
sealed I/O pins protrude the package’s side walls with the
mounting tabs on the corners of the side walls. The I/O
pins are copper Alloy 52. The pins are gold plated for long
term storage. Gold is to be removed prior to assembly. A
complete POL weighs less than 60 grams. Cooling of this
device can be accomplished by bonding the base of the
package to a metal plate or heat sink with a thermally
conductive material. The package’s mechanical outline
and I/O pins functional assignment are included in this
data sheet.
Under voltage Lockout (UVLO): An UVLO circuit prohibits the
POL from operating when the line voltage is too low to
maintain the output voltage. The POL will not start until
the line input voltage rises to approximately 4.3 volts and
will shut down when the input voltage drops below 3.9 volts.
Output Voltage Adjustment: The output voltage (Vout)
of an SBB can be adjusted to ±10% of a nominal output
voltage. One external resistor with a power rating of > 0.125 watt
is required for this function.
Following is the formula to determine an approximate
value of the resistor and how it needs to be connected to
the functional pins for a higher and a lower output voltage
with respect to the nominal output voltage.
The SBB POLs are designed, manufactured, tested, and
qualified at IR’s facility in San Jose, California which is
qualified to ISO9001 and MIL-PRF-38534 by DSCC. Flight
hardware is 100% screened and fully compliant to class K
per MIL-PRF-38534.Abbreviated screening version or
engineering model (EM) of the SBB is available for engineering
evaluation. Please refer to the Device Screening table for
details.

Circuit Description
To increase Vout, connect an adjust resistor to Vadjust pin
and Output Return pin
The SBB Series POLs utilize a non-isolated buck circuit
design topology with synchronous output rectification to
maximize efficiency. The nominal switching frequency is
400 kHz. An internal EMI filter minimizes the reflected
switching ripple current to meet most space applications at
the system level. A two-stage output filter reduces the
output ripple and noise to a very low level required by
today’s digital loads. No external filter capacitors are
required for typical design applications.

Where:
Output current is limited under any load fault condition. It
is designed to behave similar to a constant current source
with the output voltage dropping below nominal. The SBB
POL will resume normal operation when the load current
is reduced below the current limit point. This protects the
POL from both overload and short circuit conditions. The
current limit threshold exhibits a negative temperature
coefficient to reduce the possibility of thermal runaway.
Radjust is the value of the adjust resistor in Ohms()
Vnom is the nominal output voltage of the SBB

POK: The SBB POL also provides a power ok (POK)
output status signal at Pin 11. A logic high signal is
present when the POL’s output voltage is greater than
95% of the nominal output voltage. A logic low signal at
Pin 11 indicates the POL’s output voltage drops below the
output voltage threshold of 95%
Remote Sense: Output pins 4 and 5 must be connected
to +Sense pin 6 for proper operation. The +Sense pin may
be connected remotely to the output line at the load to
compensate for a voltage drop in the output line for precise
optimum output regulation. The maximum voltage compensation
in combination with the output voltage adjustment (if required)
is limited to 10% of the nominal output voltage. To enhance
the load regulation performance Input Return (Pin 2) may
be connected externally to Output Return (Pin 3)
The SBB Series POLs use a proven conservative design
methodology with careful incorporation of known radiation
performance devices and established reliability components. All
components are fully de-rated to MIL-STD-1547. Standard
design analyses include stress, thermal, failure modes
and effects (FMEA), reliability & worst case and are available
upon request.
Enable: An Enable pin is provided to remotely turn the
POL on or off. It can also be used for output sequencing
for multiple SBB POL regulators. The nominal threshold
relative to the input return (pin 2) is 2.5V. If 3.9 volts or
greater are applied to the Inhibit pin (pin 3) then the POL
will operate normally. The pin may be left open for normal
operation. A voltage of 0.4V or less will cause the SBB
POL to shut down.
Synchronization: An external synchronization port is provided to
allow the multiple SBB POLs to be synchronized to an
external frequency source to minimize the noise interference
coming from the switching operation of the POLs. The
synchronization frequency ranges from 360 kHz to 440 kHz and
the synchronization signal port can be driven from 5V logic.

Notes:
Best commercial practice.
CK is a DLA Land and Maritime (formerly DSCC) part marking used to designate a Class K compliant hybrid. The CK
marking does not indicate the hybrid is radiation certified. No suffix is a radiation rated device but not available as a
DLA qualified SMD per MIL-PRF-38534.
Any Engineering Model (EM) build with the “EM” Suffix shall only be form, fit and functional equivalent to its
Flight Model (FM) counterpart, and it may not meet the radiation performance. The EM Model shall not be expected
comply with MIL-PRF-38534 flight quality/workmanship standards, and configuration control. An EM build may use
electrical equivalent commercial grade components. IR HiRel will provide a list of non-compliance items upon request.
