DESCRIPTION

L6918A is a master device that it has to be combined with the L6918,slave, realizing a 4-phases topology, interleaved. The device kit is specifically designed to provide a high performance/high density DC/DC conversion for high current microprocessors and distributed power. Each device implements a dual-phase step-down controller with a 180° phase-shift between each phase.
