The ISL68201-99140DEMO1Z is a 6-layer board used to demonstrate a compact 17mm x 17mm 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 ISL68201 is a single-phase synchronous buck PWM controller featuring Renesas' 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 and a wide 0.5V to 5.5V output range. It includes programmable functions and telemetries for easy use and high system flexibility using an SMBus, PMBus or I2C interface.
The ISL99140 is a high performance DrMOS power stage designed for high frequency power conversion. By combining a high performance FET driver and MOSFETs in an advanced package, high density DC/DC converters can be created.
The PMBus dongle (ISLUSBEVAL1Z), i.e., USB-to-PMBus™ adapter, and USB cable are included in the demonstration kit. Renesas' PowerNavigator™ evaluation software can be installed from Renesas' website and evaluate the full PMBus functionality of the part using a PC running Microsoft Windows 7 or 8.
