Differential Remote Sensing Evaluation Board
The ISL70002SEHEVAL3Z evaluation board is designed to demonstrate the features of the ISL70002SEH or ISL73002SEH, TID and SEE hardened 22A synchronous buck regulator...
概要
説明
The ISL73002SEH 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 ISL73002SEH 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 ISL73002SEH uses peak current-mode control with integrated error amp compensation and pin-selectable slope compensation. The 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 ISL73002SEH 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.
