1 Suggested Point-of-Load Designs

Table 1-1 highlights the latest POL DC/DC converters with integrated MOSFETs and controllers suitable for Raptor Lake applications. The suggested devices are selected to accommodate different input voltage and control mode requirements over a wide range of output current. The featured devices in the left column accommodate a maximum input voltage of 22 V or greater, and are designed to achieve fast load-transient response with an adaptive on-time control mode, high light and full-load efficiency, and low quiescent current.

Several devices include an integrated programmable voltage identification (VID) supporting the processor's adaptive voltage requirements. The alternate devices in the right column employ fixed-frequency current-mode control with frequency synchronization useful in noise-sensitive industrial applications, and operate up to a 17 V input. If VID is required with alternative devices, consider the LM10011 VID voltage programmer in addition to the converter's resistor divider network.
