DESCRIPTION
The device 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 ex-
ternal power mos providing low switching losses.
The device assures a fast protection against load
over current and load over/under voltage. An inter-
nal crowbar is provided turning on the low side
mosfet if an over-voltage is detected.
In case of over-current, the system works in Con-
stant Current mode until UVP
