Description

The L6710 implements a two phase step-down controller with a 180 phase-shift between each phase with integrated high current drivers in a compact 10x10mm body package with exposed pad. A precise 6-bit digital to analog converter (DAC) allows adjusting the output voltage from 0.8375V to 1.6000V with 12.5mV binary steps managing Dynamic VID code changes.

The high precision internal reference assures the selected output voltage to be within 0.5% over line and temperature variations. The high peak current gate drive affords to have fast switching to the external power mos providing low switching losses.

The L6710 assures a fast protection against load over current and load over/under voltage. An internal crowbar is provided turning on the low side mosfet if an over-voltage is detected.

In case of over-current, the system works in Constant Current mode until UVP
