Intersil Announces Highly Integrated DC/DC Digital PWM Controller for Densely Populated Infrastructure Power Systems

by donpedro

Intersil Corporation announced the ZL8801 dual-phase, DC/DC digital PWM controller. The ZL8801 expands Intersil’s fourth generation controller family by enabling a simple dual

phase solution for higher current applications ranging from 40A to 100A. With the ability to current share across multiple devices, its range can be extended up to 300 amps for high-end FPGAs and ASICs employed in densely populated power supplies in servers, storage equipment and basestations. Used in conjunction with Intersil’s easy-to-use PowerNavigator™ graphical user interface (GUI), the ZL8801 simplifies system power conversion and speeds the design process. The ZL8801 utilizes Intersil’s latest advances in digital power technology, leveraging the patented ChargeMode™ control loop architecture to deliver transient response performance that’s far superior to today’s analog controllers. The ZL8801 supports Intersil’s proprietary DDC (digital DC) bus for inter-controller communication. Configuration is easily managed with the graphical PowerNavigator tool to provide drag and drop sequencing control, which is autonomously managed in system by the ZL8801.
