Beschreibung
The ISL68200 is a single-phase synchronous buck PWMcontroller featuring Intersil’s proprietary R4™ Technology,which has extremely fast transient performance, accuratelyregulated frequency control, and all internal compensation.The ISL68200 supports a wide 4.5V to 24V input voltage rangeand a wide 0.5V to 5.5V output range. It includesprogrammable functions and telemetries for easy use andhigh system flexibility using SMBus, PMBus, or I2C interface.See the ISL68200 datasheet for more details.The ISL68200DEMO1Z is a 6-layer board demonstrating acompact 17mmx17mm 20A synchronous buck converter.Transient performance, fault protections, DC/AC regulations,PMBus programming, power sequencing, margining, and otherfeatures can be evaluated using this board.The PMBus dongle (ZLUSBEVAL3Z USB-to-PMBus adapter) andUSB cable are included with the demonstration board.Intersil’s evaluation software can be installed from Intersil’swebsite and be used to evaluate the full PMBus functionality ofthe part using a PC running Microsoft Windows.
Eigenschaften
