L6919E Datasheet (STMicroelectronics) - 5-BIT PROGRAMMABLE DUAL-PHASE CONTROLLER

L6919E, 5-BIT PROGRAMMABLE DUAL-PHASE CONTROLLER

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
