Intersil Corp. has launched the ZL2008, a high-performance synchronous step-down DC/DC converter with pin-strap compensation and current sharing. Based on Zilker’s patented Digital-DC technology, Intersil’s ZL2008 is designed for digital power supply module and system designers who demand easy-to-use board-level power supply configuration to keep ahead of rapidly changing market requirements.
The ZL2008 is a synchronous buck converter with integrated 3A MOSFET drivers that operate on single supply from 3V to 14V. Output voltages range from 0.54V to 5.5V with ±1 percent output voltage accuracy and 200kHz to 1.4MHz operation. In addition, there is current sharing with individual phase enable/disable pins, optional I˛C/SMBus configuration, and external clock synchronization.
Power management features include coincidental/ratiometric tracking, power up/down sequencing, voltage margining, and voltage and current monitoring as well as internal temperature monitoring. There is extensive fault handling for all parameters thanks to the on-board Snapshot parameter capture. The product also has on-chip non-volatile memory (NVM) for storing custom configurations.
The ZL2008 is available in 6x6mm 36-lead QFN packages.
