Features

* control VID voltage transition for dynamic VID changes and eliminate both undervoltage and overvoltage overshoot. The PWRGD signal is accurate during VID code changes for the MAX8525 to avoid any false fault signal. Adjustable foldback current-limit and overvoltage protection provide for a robust de

Applications

* The switching frequency of the MAX8524/MAX8525 is adjustable from 150kHz to 1.2MHz, permitting loop bandwidths of up to 200kHz. Peak current-mode control provides fast transient response and reduces cost. A proprietary current-sharing scheme reduces current imbalance between phases to less than 5%
