描述
The ISL70001ASEH 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 6A for TJ <+145 °C. The ISL70001ASEH utilizes 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 an application where two POLs are needed, two ISL70001ASEH 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 ISL70001ASEH incorporates fault protection for the regulator. The protection circuits include input undervoltage, output undervoltage and output overcurrent. High integration and class-leading radiation tolerance make the ISL70001ASEH 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.
