Product overview
Description
L6756D is a two-to-four phase controller designed to power Intels 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
