Description
The device implements a three phase step-down
controller with a 120° phase-shift between each
phase with integrated high current drivers in a
compact 7x7mm body package with exposed pad.
The device embeds selectable DAC: the output
voltage ranges from 0.8185V to 1.5810V with
12.5mV steps (VID_SEL = OPEN) or from 0.800V
to 1.550V with 25mV steps (VID_SEL = GND;
VID5 drives an optional +25mV offset) managing
dynamic VID with 0.5% accuracy over line and
temp variations. Additional programmable offset
can be added to the voltage reference with a
single external resistor.
The device 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.
Selectable current reading adds flexibility in
system design.
