Overview
L6716 2/3/4 phase controller with embedded drivers for Intel® VR11.
1 Features ■ Load transient boost LTB Technology™ to minimize the number of output capacitors ■ 2 or 3-phase operation with internal driver ■ 4-phase operation with external PWM driver signal ■ PSI input with programmable strategy ■ Imon output ■ 0.
5% output voltage accuracy ■ 8-bit programmable output up to 1.
60000 V - Intel VR11.
1 DAC - backward compatible with VR10/VR11 ■ 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 ■ SS_END and OUTEN signal ■ VFQFPN-48 7x7 mm package with exposed pad Applications ■ High current VRM/VRD for desktop / server / workstation CPUs ■ High density DC/DC converters VFQFPN-48 - 7 x 7 mm Description 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 overcurrent and under / overvoltage (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 overcurrent, the system works in constant current mode until UVP.
