Digital-DC™ Integrated Power Management and Conversion IC  
Description  
Features  
The ZL2005 is an innovative mixed-signal power  
management and conversion IC that combines a com-  
pact, efficient, synchronous DC/DC buck controller,  
adaptive drivers and key power and thermal manage-  
ment functions in one IC, providing flexibility and  
scalability while decreasing board space requirements  
and design complexity. Zilker Labs’ Digital-DC tech-  
nology enables a unique blend of performance and  
features not available in either traditional analog or  
newer digital approaches, resolving the issues associ-  
ated with providing multiple, low-voltage power  
domains on a single PCB.

± 1% output accuracy  
Internal 3 A drivers support >30 A power stage  
Fast load transient response  
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.  
Phase interleaving  
RoHS compliant (6 x 6 mm) QFN package  
Applications  
All operating features can be configured by simple  
pin-strap selection, resistor selection or through the  
on-board serial port. The PMBus™-compliant  
ZL2005 uses the SMBus™ serial interface for com-  
munication with other Digital-DC products or a host  
controller.
