DESCRIPTION
The device is a power supply controller specifically designed to proVIDe a high performance DC/DC conversion for high Current microprocessors. The device implements a dual-phase step-down controller with a 180° phase-shift between each phase. A precise 5-bit digital to analog converter (DAC) allows adjusting the output voltage from 0.800V to 1.550V with 25mV binary steps managing On-The-Fly VID code changes.
The high precision internal reference assures the selected output voltage to be within ±0.6%. The high peak Current gate drive affords to have fast switching to the external power mos proVIDing low switching losses.
The device assures a fast protection against Load over Current and Load over/under voltage. An internal crowbar is proVIDed turning on the low side mosfet if an over-voltage is detected. In case of over-Current, the system works in Constant Current mode.
