HIGH RELIABILITY CLASS K HYBRID,
RADIATION HARDENED, NON-ISOLATED
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 rating of 14A. The POLs are class
K qualified per MIL-PRF-38534. These products are
designed to operate continuously on board a space

(MEO), low earth orbit (LEO), deep space, and for other
challenging radiation design applications.

The SBB POL is a non isolated synchronous buck
regulator. It incorporates IR’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.

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.
Undervoltage 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.
To reduce Vout, connect an adjust resistor to

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.
To increase Vout, connect an adjust resistor to
Vadjust pin and Output Return pin

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.

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).
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%
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
derated 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
sequenceing 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.

nominal.
6. Load step transition time ≤ 1.0 µs/A for 3.3V & 2.5V models and ≤ 0.1 µs/A for 1.0V, 1.2V, 1.5V & 1.8V models.
7. Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1% of its
steady state value.
8. Line step transition time ≤ 10 µs.
9. Turn-on delay time from either a step application of input power or a logic low to a logic high transition on the

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 Land and Maritime qualified SMD per MIL-PRF-38534.
International Rectifier currently does not have a DLA Land and Maritime certified Radiation Hardness Assurance Program.
