1 DAC High current embedded driver High output voltage accuracy Programmable droop function Imon output Load transient boost LTB Technology™ to minimize the number of output capacitors Full differential current sense across inductor Differential remote voltage sensing Adjustable voltage offset LSLess startup to manage pre-biased output Feedback disconnection protection Preliminary overvoltage protection Programmable overcurrent protection Programmable overvoltage protection Adjustable switching frequency SSEND and OUTEN signal VFQFPN-40 6x6 mm package with exp.
pad The device implements a single phase step-down controller with integrated high current driver in a compact 6x6 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.
