描述 Description

The ZL2005P is an innovative mixed-signal power

conversion and management 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.

The ZL2005P is designed to be configured either as a

standard ZL2005 or as POLA/DOSA compatible

device.

All operating features can be configured by simple

pin-strap selection, resistor selection or through the

on-board serial port. The PMBus?-compliant

ZL2005P uses the SMBus? serial interface for communication with other Digital-DC products or a host

controller.
