Rad Hard and SEE Hard 6A Synchronous Buck Regulator ISL70001SEH

The ISL70001SEH is a radiation hardened and SEE hardened high efficiency monolithic synchronous buck regulator with integrated MOSFETs. This single chip power solution operates over an input voltage range of 3V to 5.5V and provides a tightly regulated output voltage that is externally adjustable from 0.8V to ~85% of the input voltage. Output load current capacity is 6A for TJ < +145℃.

High integration and class leading radiation tolerance makes the ISL70001SEH an ideal choice to power many of today’s small form factor applications. Two devices can be synchronized to provide a complete power solution for large scale digital ICs, like field programmable gate arrays (FPGAs), that require separate core and I/O voltages.
