L6716

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 a...
