Rad Hard FPGA Power Solution
Intersil offers a complete solution for powering Rad Hard FPGAs

• Designed for SET immunity
• Optimized to power multi-channel FPGA devices

Many space grade FPGAs require a core voltage of 1.0V, which is supplied by the ISL70002SEH, an auxiliary voltage of 2.5V, which is supplied by the ISL70001SEH, and an I/O voltage of 3.3V which is supplied by the ISL75051RH.

The ISL70001SEH and ISL70002SEH are total dose and SEE hardened high efficiency, monolithic synchronous buck regulators with integrated MOSFETs. These single chip power solutions operate over an input voltage range of 3V to 5.5V and provide a tightly regulated output voltage that is externally adjustable from 0.8V to ~85% of the input voltage. The ISL70001SEH can provide up to 6A (TJ ≤ +145°C) of output current while the ISL70002SEH can provide up to 12A (TJ ≤ +150°C) of output current. 

The ISL75051SRH is a radiation hardened, low voltage, high current, single output LDO specified for up to 3.0A of continuous output current. It can operate over an input voltage range of 2.2V to 6.0V and is capable of providing output voltages of 0.8V to 5V with an external resistor divider. Dropout voltages as low as 65mV can be realized with this device.
