The ISL70003SEH embarks as the industry’s first radiation-hardened 12V input point-of-load (POL) synchronous buck switching regulator capable of operating over an input range of 3V to 13.2V. Integrating upper and lower switching MOSFETs, the device employs an advanced packaging technique that eliminates the need for an external heat sink. It also uses a voltage mode control architecture with feed-forward and switches at a selectable frequency of 500 kHz or 300 kHz. Loop compensation is externally adjustable to allow for an optimum balance between stability and output dynamic performance. Other features include a ±5% voltage accuracy, ±1% reference voltage variation over line, temperature and radiation, ±3% SET performance, and a peak efficiency up to 95%.
