Rev 8.00
October 1, 2015 Radiation Hardened and SEE Hardened 12A 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
capacity is 12A for TJ ≤ +150°C. The two ISL70002SEH
devices configured to current share can provide 19A total
output current, assuming В±27% worst-case current share
accuracy.
The ISL70002SEH utilizes 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
180В° 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 …
