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.
Features
▪ Separate VOUT and GND Force and Sense
terminals
▪ Optional 2x2m Ω emulated trace resistance
included on board
▪ 3V to 5.5V input
▪ Adjustable V
OUT
from 0.6V to 0.85×V
IN
Recommended Equipment
▪ A 6V power supply capable of at least 10A
▪ An electronic load capable of sinking at least 12A
▪ Three Digital Multimeters (DMMs)
▪ A 500MHz four-channel oscilloscope
▪ Optional: One differential voltage probe to measure
one signal with respect to a different ground.
