The device features LTB technology® to provide the fastest response to load transients thus minimizing the output filter composition. L6750 features Power Manager I2C to implement overspeeding and other power management options without using any external component. The device embeds selectable DAC: Output Voltage is programmable up to 1.6000V (Intel VR10 and VR11.x DACs) or up to 1.550V (AMD 6bit DAC) managing DVID transitions with ±0.5% output voltage accuracy over line, load and temperature variations.
