2 www.irf.com SBB SERIES Single Output Circuit Description 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. 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. 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. 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. 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. 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. To reduce Vout, connect an adjust resistor to Vadjust pin and Output pin Vnom Vout Vnom Vout Radj 22 1028011280 To increase Vout, connect an adjust resistor to Vadjust pin and Output Return pin Vnom Vout Vnom Vout Radj 22 102809280 Where: Radjust is the value of the adjust resistor in Ohms( Ω) Vnom is the nominal output voltage of the SBB

www.irf.com 3 SBB SERIES Single Output 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. 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. 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).
