Description
The device implements a two-to-four phases step-
down controller with three integrated high current
drivers in a compact 7x7 mm body package with
exposed pad.
Load transient boost LTB Technology™ reduces
system cost by providing the fastest response to
load transition therefore requiring less bulk and
ceramic output capacitors to satisfy load transient
requirements.
The device embeds VR11.x DACs: the output
voltage ranges up to 1.60000 V managing D-VID
with ± 0.5 % output voltage accuracy over line
and temperature variations.
The controller assures fast protection against load
over current and under / over voltage (in this last
case also before UVLO). Feedback disconnection
prevents from damaging the load in case of
disconnections in the system board.
In case of over-current, the system works in
constant current mode until UVP.
