Renesas ISL99140 | Demoboard ISL68201-99140DEMO1Z

Description

The ISL68201 is a single-phase synchronous buck PWM controller featuring Intersil’s proprietary R4™ Technology, which has extremely fast transient performance, accurately regulated frequency control and all internal compensation. The ISL68201 supports a wide 4.5V to 24V input voltage range anda wide 0.5V to 5.5V output range. It includes programmable functions and telemetries for easy use and high system flexibility using SMBus, PMBus, or I2C interface. See theISL68201 datasheet for more details.The ISL99140 is a high performance DrMOS power stage designed for high frequency power conversion. By combining ahigh performance FET driver and MOSFETs in an advanced package, high density DC/DC converters may be created.The ISL68201-99140DEMO1Z is a 6-layer board demonstrating a compact 17mmx17mm 35A synchronous buck converter. Transient performance, fault protections, DC/AC regulations, PMBus programming, power sequencing, margining and other features can be evaluated using this board.The PMBus dongle (ZLUSBEVAL3Z), i.e., USB-to-PMBus™ adapter, and USB cable are included in the demonstration kit.Intersil’s PowerNavigator™ evaluation software can be installed from Intersil’s website and evaluate the full PMBusfunctionality of the part using a PC running Microsoft Windows 7 or 8.
