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.
