Overview

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.
