ISL70002SEH

DATASHEET Radiation Hardened and SEE Hardened 12A Synchronous Buck Regulator with Current Sharing ISL70002SEH 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 ±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 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.
