a tri-level output that provides excellent protection against faults by driving a mid scale voltage to signal the power stage to enter a Hi-Z condition. The ISL73847SEH operates across the military temperature range from -55°C to +125°C and is available in a 24 Ld hermetically sealed Ceramic Dual Flatpack (CDFP) package or in die form.

Radiation Hardened Single/Dual Phase Current Mode PWM Controller
Datasheet
The ISL73847SEH is a synchronous buck controller that can operate as a single or dual-phase controller. It works with the ISL73041SEH (half-bridge GaN FET driver) to generate point-of-load voltage rails for commercial space applications.
It accepts an input voltage range of 4.5V to 19V with a programmable PWM output switching frequency between 250kHz and 1.5MHz with a single resistor. The output can regulate a voltage upwards of 600mV and is limited on the top end by the minimum off time and selected switching frequency.
The wide input voltage range makes it a suitable power supply option for a high-current FPGA core and other general-purpose power solutions.
