ISL71001M50NZ

The ISL71001M is a radiation tolerant and high efficiency monolithic synchronous buck regulator with integrated MOSFETs. This single-chip power solution operates across 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 with an output load current capacity of 6A. The ISL71001M is available in a plastic 64 Ld Thin Quad Flatpack (EP-TQFP) package. The ISL71001M uses peak current-mode control for excellent output load transient response and features integrated compensation and switches at a fixed frequency of 1MHz to reduce component size and count. In applications where two regulators are needed, two ISL71001M devices can be synchronized 180° out-of-phase to reduce the overall input RMS ripple current. The internal synchronous power switches are optimized for high efficiency and good thermal performance. The ISL71001M incorporates fault protection for the regulator. The protection circuits include input undervoltage, output undervoltage, and output overcurrent. High integration makes the ISL71001M an ideal choice to power many of today’s 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.
