STMicroelectronics L6917 Dual-Phase Controller Datasheet
The L6917 is a power supply controller designed for high-performance DC/DC conversion in high-current microprocessor applications. It implements a dual-phase step-down controller with a 180° phase-shift and features a precise 5-bit digital-to-analog converter (DAC) for adjusting the output voltage from 1.100V to 1.850V with 25mV steps.
The device includes integrated high-current gate drivers capable of up to 2A gate current, ensuring fast switching and low losses. It offers protection features such as overvoltage protection (OVP), overcurrent protection (OCP), and an internal crowbar circuit. The internal oscillator runs at 300 kHz but is externally adjustable up to 1 MHz.
