DATASHEET ISL70002SEH, ISL73002SEH Radiation Hardened and SEE Hardened 22A Synchronous Buck Regulators with Current Sharing FN8264 Rev.12.01 Mar 31, 2022 The ISL70002SEH and ISL73002SEH (ISL7x002SEH) are radiation hardened and SEE hardened high-efficiency monolithic, synchronous buck regulators 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 ISL7x002SEH devices, configured to current share, can provide up to 38A of total output current at PVIN ≤ 5.
