APPLICATIONS

HIGH CURRENT DC/DC CONVERTERS

DISTRIBUTED POWER SUPPLY

DESCRIPTION

The device implements a dual-phase step-down con-

troller with a 180 phase-shift between each phase

optimized for high current DC/DC applications.

Output voltage can be programmed through the in-

tegrated DAC from 0.900V to 3.300V; program-

ming 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 loss-

es along distribution line.

The device 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 Cur-

rent mode: when Under Voltage is detected, the

device resets, restarting operation.
