Description

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.

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 on-board serial port. The PMBus™-compliant ZL2005 uses the SMBus™ serial interface for communication with other Digital-DC products or a host controller.

Applications

• Servers/storage equipment
• Telecom/datacom equipment
• Power supplies (memory, DSP, ASIC, FPGA)
• Point of load converters
