概述
描述
The ISL68201-99135DEMO1Z is a 6-layer board used to demonstrate a compact 13mm x 13mm 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 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 ISL99135B is a DrMOS power stage compatible with Renesas' 5V PWM controllers (such as ISL6398, ISL637x, ISL633x, ISL636x, ISL9585x, and ISL68201). 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 3.5 x 5 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.

视频和培训
These PMBus™ compatible single-phase digital hybrid DC/DC controllers are ideal for point-of-load (POL) conversions. They support a wide range of applications, including FPGAs, DSPs, ASICs, processors, and general-purpose system rails.
The ISL68200 model is integrated with MOSFET drivers, making power supply design simpler. The ISL68201 features a PWM output for efficient performance. Both models are designed to meet the demands of data centers and wireless infrastructure applications.
