ISL70002SEHEVAL3Z
Differential Remote Sensing Evaluation Board
The ISL70002SEHEVAL3Z evaluation board is
designed to demonstrate the features of the
ISL70002SEH, a TID and SEE hardened 22A
synchronous buck regulator IC with integrated
MOSFETs intended for space applications. For more
detailed information about the ISL70002SEH, refer to
the ISL70002SEH Datasheet.
The ISL70002SEHEVAL3Z is similar to the
ISL70002SEHEVAL1Z, but AGND is separated from
PGND. This allows remote ground sensing to
compensate for voltage loss in the ground path.
Ground sensing is an important feature when
providing a tightly regulated core voltage for a FPGA
or microcontroller.
