Description

The ISL68201 is a single-phase synchronous buck PWMcontroller featuring Intersil’s proprietary R4™ Technology,which has extremely fast transient performance, accuratelyregulated frequency control and all internal compensation. TheISL68201 supports a wide 4.5V to 24V input voltage range anda wide 0.5V to 5.5V output range. It includes programmablefunctions and telemetries for easy use and high systemflexibility using SMBus, PMBus, or I2C interface. See theISL68201 datasheet for more details.The ISL99140 is a high performance DrMOS power stagedesigned for high frequency power conversion. By combining ahigh performance FET driver and MOSFETs in an advancedpackage, high density DC/DC converters may be created.The ISL68201-99140DEMO1Z is a 6-layer boarddemonstrating a compact 17mmx17mm 35A synchronousbuck converter. Transient performance, fault protections,DC/AC regulations, PMBus programming, power sequencing,margining and other features can be evaluated using thisboard.

Features

  • 35A synchronous buck converter with PMBus control
  • On-board transient load with adjustable di/dt
  • Configurable through resistor pins
  • Cascadable PMBus connectors
  • Integrated LDOs for single rail solution
  • Enable switch and power-good indicator
  • All ceramics solution with SP capacitor footprint option
