The GH Series of devices is suitable for designs using new digital signal processors and FPGA technologies that require a supply voltage as low as 1.0 V. Key features include 18 V to 40 V input range, total ionization dose (TID) of over 100 krad (Si), single event effect (SEE) (Heavy Ions) with rated LET greater than 82 MeV.cm²/mg, internal EMI filter complying with most major satellite power buses, and a weight of less than 110 g.

The GH Series was developed using a proven space-level design methodology that includes selection of established reliable components and fully de-rated to the requirements of MIL-STD-1547. The devices feature magnetically coupled feedback to insure robust operation under the intended radiation environments.

The output models range from 1.0 V to 5.0 V with current rating of up to 20 A and high efficiency up to 87 percent. Output is adjustable with an external resistor for a precise output voltage setting with the adjustment range of ±10% of the rated output voltage. Other key features include remote sense compensation, remote output on/off control via Inhibit pin, input under-voltage protection with under-voltage lockout (UVLO), and synchronization for applications with multiple converters.

Pricing for the GH2803R3S begins at US $17,500 each for 5-10 unit quantities. Production orders are available immediately.
