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
overcurrent and under / overvoltage (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 overcurrent, the system works in
constant current mode until UVP.
