ZL2005ALNFT1集成電路（IC）的PMIC-穩(wěn)壓器-DCDC開(kāi)關(guān)式控制器規(guī)格書(shū)PDF中文資料

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.
