Description :

L6706 VR11.1 single phase controller with integrated driver Features 8-bit programmable output up to 1.60000 V Intel VR11.1 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 6×6 mm package with exp. pad 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. VFQFPN-40 6 x 6 mm Description Applications VTT and VAXG rails CPU power supply High density DC/DC converters Table 1.
