International Rectifier Corp. (IR, El Segundo, CA) introduced a new line of 10W, radiation-hardened, "off-the-shelf," dc/dc converters, the S Series, which are available either unscreened or screened to Class K per MIL-PRF-38534. The new S Series converters are a suitable choice for low-power circuits such as analog and digital control power systems, as well as signal amplifiers and sensors in geo-synchronous and low earth orbit satellite applications.
The new converters feature 28Vdc input, with single-out or dual-output configurations, and operate up to 81% efficiency. The new S Series converter line includes various functional and protection features such as under-voltage lockout, output over-voltage limiter, on/off inhibit, and short-circuit and overload protection. Other features include magnetically coupled feedback, with radiation hardness of 100krads total ionizing dose. Other features include an 18Vdc to 40Vdc input range; up to 10W of output power; a single and dual output of 3.3V, 5V, 12V, 15V, ±5V, ±12V and ±15V; and a -55°C to +125°C operating temperature.
The new S Series converters are available immediately. The new devices are available either unscreened or screened to Class K per MIL-PRF-38534. These products are subject to US export control laws and regulations.
