International Rectifier CHiL PWM controllers

A family of CHiL digital PWM controllers, that shrinks footprint and improves efficiency in a variety of mid-range to high-end and extreme server, desktop and computing applications, has become available.

Six devices meet Intel VR12 and VR12.5 and AMD SVI1 and SVI2 specifications and support multiphase designs from one to eight phases, operating one to two loops.

These third generation devices offers efficiency shaping features such as phase shedding and variable gate drive with enhanced algorithms, including PID scaling and phase current balancing.

The solution architecture supports the high di/dt transients from high-end processors.

As a result of a new adaptive transient algorithm, the transients can be met with fewer phases and fewer capacitors, to shrink system size.
