Resources for ISL70002SEH
Description
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 TJ ≤ +125°C. Two ISL70002SEH devices, configured to current share, can provide up to 38A of total output current at PVIN ≤ 5. 5V for TJ ≤ +125 °C assuming ±27% worst-case current share accuracy. 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.
