Description

The L6712A  implements a dual-phase step-down controller with a 180 phase-shift between each phase optimized for high current DC/DC applications.

Output voltage can be programmed through the integrated DAC from 0.900V to 3.300V; programming the "111" code, an external reference from 0.800V to 3.300V is used for the regulation.

Programmable Remote Sense Amplifier avoids use of external resistor divider and recovers losses along distribution line.

The L6712A assures a fast protection against load over current and Over / Under voltage.An internal crowbar is provided turning on the low side mosfet if Over-voltage is detected.

Output current is limited working in Constant Current mode: when Under Voltage is detected, the L6712A resets, restarting operation.
