INTERNATIONAL RECTIFIER Versatile family of CHiL digital PWM controllers that dramatically shrinks footprint and improves efficiency in a variety of mid-range to high-end and extreme server, desktop, and computing applications. IR’s six new devices meet Intel VR12 and VR12.5 and AMD SVI1 and SVI2 specifications, and support multiphase designs from 1 to 8 phases operating 1 to 2 loops. These new third generation CHiL devices offer efficiency shaping features such as phase shedding and variable gate drive with enhanced algorithms including PID scaling (when shedding phases) and phase current balancing to ensure maximum efficiency.
