DATASHEET
ISL70002SEH
Radiation Hardened and SEE Hardened 18A Synchronous Buck Regulator with
Current Sharing
The
ISL70002SEH
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
capability is primarily determined by PVIN voltage with up to
22A for a single IC at PVIN
5.5V for T
J
+125°C. Two
ISL70002SEH devices configured to current share can
provide up to 38A of total output current at PVIN
5.5V for
T
J
+125°C assuming ±27% worst-case current share
accuracy.
Refer to the Features section for maximum output current
detailed constraints and recommendations.
The ISL70002SEH uses peak current-mode control with
integrated error amp compensation and pin selectable slope
compensation. Switching frequency is also pin selectable to
either 1MHz or 500kHz. Two devices can be synchronized
180° out-of-phase to reduce input RMS ripple current.
High integration makes the ISL70002SEH an ideal choice to
power 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.
