The device implements a single phase step-down controller with integrated high current driver in a compact 6×6 mm body package with exposed pad.
The device embeds VR11.x DACs: the output voltage ranges up to 1.60000 V managing D-VID with high output voltage accuracy over line and temperature variations.
Imon capability guarantee full compatibility with VR11.1 enabling additional power saving technique.

Programmable droop function allows to supply all the latest Intel CPU rails.
Load transient boost LTB Technology™ reduces system cost by providing the fastest response to load transition.

The controller assures fast protection against load over current and under / over voltage. 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. […]
