L6716 2/3/4 phase controller with embedded drivers for Intel VR11.1

The device implements a two-to-four phases stepdown controller with three integrated high current drivers in a compact 7x7 mm body package with exposed pad.

Load transient boost LTB Technology™ reduces system cost by providing the fastest response to load transition therefore requiring less bulk and ceramic output capacitors to satisfy load transient requirements.

The device embeds VR11.x DACs: the output voltage ranges up to 1.60000 V managing D-VID with ± 0.5 % output voltage accuracy over line and temperature variations.

The controller assures fast protection against load over current and under / over voltage (in this last case also before UVLO). Feedback disconnection prevents from damaging the load in case of disconnections in the system board.

In case of over-current, the system works in constant current mode until UVP.
