ST L6917 handbook

The document describes a power supply controller specifically designed to provide 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 1.100V to 1.850V with 25mV binary steps. The high-precision internal reference ensures the selected output voltage to be within ±0.8%. The high peak current gate drive affords fast switching to the external power MOS, providing low switching losses. The device ensures fast protection against load overcurrent and load over/undervoltage. An internal crowbar is provided, turning on the low side MOSFET's RdsON or a sense resistor for overcurrent protection.
