ISL68201-99135DEMO1Z

Single-Phase R4™ Digital Hybrid PWM Controller and 35A DrMOS Module Demonstration Board

Description

The ISL68201-99135DEMO1Z is a 6-layer board demonstrating a compact 13mmx13mm 20A 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 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 and a 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.

The ISL99135B is a DrMOS power stage compatible with Intersil's 5V PWM controllers (such as ISL6398, ISL637x, ISL633x, ISL636x, ISL9585x and ISL68201). They use 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 (ZLUSBEVAL3Z), i.e., USB-to-PMBus™ adapter, and USB cable are included in the demonstration kit. Download PowerNavigator™ software to evaluate the full PMBus functionality of the ISL68201.
