Description
The device implements a one-to-three phases
step-down controller with three integrated high
current drivers in a compact 6x6 mm body
package with exposed pad.
Output voltage can be selected trough serial and
parallel VID up to 1.3500 V and managing D-VID
with ±2% output voltage accuracy.
The device manages serial BUS communication
to program power management functionalities as
well as monitoring.
The device features automatic startup phase
procedure and phases self detection for safe
operation.
The controller embeds 5 V LDO regulator
increasing design flexibility.
Advanced IC and VRM thermal management to
assure robust design and safe operation.
The controller assures fast protection against load
overcurrent and under / overvoltage.
L6788A is available in VPQFN 6 x 6 mm package.
