ZL6105
Digital DC/DC Controller with Drivers and Auto Compensation
The ZL6105 is a digital power controller with integrated
MOSFET drivers. Auto compensation eliminates the need for
manual compensation design work. Adaptive performance
optimization algorithms improve power conversion efficiency.
Zilker Labs Digital-DC™ technology enables a blend of power
conversion performance and power management features.
The ZL6105 is designed to be a flexible building block for DC
power and can be easily adapted to designs ranging from a
single-phase power supply operating from a 3.3V to a
multiphase current sharing supply operating from a 12V input.
The ZL6105 eliminates the need for complicated power supply
managers as well as numerous external discrete components.
The ZL6105 uses the I
2
C/SMBus™ with PMBus™ protocol for
communication with a host controller and the Digital-DC bus
for communication between Zilker Labs devices.
The ZL6105 is pin for pin compatible with the ZL2008. The
POLA V
OUT
table and compensation table have been removed.
A new single resistor V
OUT
table and the Auto Compensation
feature have been added.
