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 con-

version for high current microprocessors and distrib-

uted power. Each device implements a dual-phase

step-down controller with a 180° phase-shift between

each phase.

Rdson or Rsense CURRENT SENSING

1200KHz EFFECTIVE SWITCHING

FREQUENCY, EXTERNALLY ADJUSTABLE

■

POWER GOOD OUTPUT AND INHIBIT

PACKAGE: SO28

A precise 5-bit DAC allows adjusting the output volt-

age from 1.100V to 1.850V with 25mV binary steps.

The high peak current gate drives affords to have

high system switching frequency, typically of

1200KHz, and higher by external adjustement.

The device kit assure a fast protection against OVP,

UVP and OCP. An internal crowbar, by turning on the

low side mosfets, eliminates the need of external pro-

tection. In case of over-current, the system works in

Constant Current mode.
