L6756D 2/3/4 phase buck controller for VR10, VR11.1 and AM2 processor applications

L6756D is a two-to-four phase controller designed to power Intel’s most demanding processors and, most in general, low-voltage, high-current power supplies. The device features LTB Technology® to provide the fastest response to load transients thus minimizing the output filter composition.

L6756D embeds selectable DAC: output voltage is programmable up to 1.6000 V (Intel VR10 and VR11.x DACs) managing DVID transitions with ±0.5% output voltage accuracy over line, load and temperature variations.

The device assures fast protection against load over current and under / over voltage. Feedback disconnection prevents from damaging the load in case of misconnections in the system board.

Low-side-less start-up allows soft-start over prebiased output avoiding dangerous current return through the main inductors as well as negative spike at the load side.

L6756D is available in VFQFPN 6x6 mm package
