February 23, 2011 Description Features The ZL2005 is an innovative mixed-signal power
management and conversion IC that combines a compact, efficient, synchronous DC/DC buck controller,
adaptive drivers and key power and thermal management functions in one IC, providing flexibility and
scalability while decreasing board space requirements
and design complexity. Zilker Labs’ Digital-DC technology enables a unique blend of performance and
features not available in either traditional analog or
newer digital approaches, resolving the issues associated with providing multiple, low-voltage power
domains on a single PCB. Power Management Digital soft start/stop Precision delay and ramp-up Power good/enable Voltage tracking, sequencing and margining Voltage/current/temperature monitoring I2C/SMBus communication Output overvoltage and overcurrent protection PMBus compliant
Power Conversion Efficient synchronous buck controller 3 V to 14 V input range 0.6 V to 5.5 V output range В± 1% output accuracy Internal 3 A drivers support >30 A power stage Fast load transient response Phase interleaving RoHS compliant (6 x 6 mm) QFN package The ZL2005 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 3.3 V input to a multi-phase supply operating
from a 12 V input. The ZL2005 eliminates the need
for complicated power supply managers as well as
numerous external discrete components.
All operating features can be configured by simple
pin-strap selection, resistor selection or through the …
