SBB502R5S Datasheet | International Rectifier

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 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. The SBB POL is a non isolated synchronous buck regulator. It incorporates IR Hi Rel’s heritage-rich ponents 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 pensate for voltage drops in the output lines. This feature , in bination with the output adjustment capability, enables an output voltage of a POL to be accurately set as needed. With its excellent efficiency performance, SBB POLs are ideal as the point of load regulators for the distributed power architecture (DPA) design systems. Other key benefits include excellent dynamic load response, precise voltage setting, remote output voltage sensing and synchronization.
