The ISL68201-99125DEMO1Z is a 6-layer board used to demonstrate a compact 13mm x 13mm 16A 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 ISL99125B is a DrMOS power stage compatible with Renesas' 5V PWM controllers. They use a DCR sensing network and associated thermal compensation. Light-load efficiency is supported via a dedicated FCCM control pin. An industry leading thermally enhanced 3.5x5 QFN 24 Ld package allows minimal overall PCB real estate.
The PMBus dongle (ISLUSBEVAL1Z), i.e., USB-to-PMBus™ adapter, and USB cable are included in the demonstration kit. Download the PowerNavigator™ software to evaluate the full PMBus functionality of the ISL68201.
