Demonstration Board User Guide
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 I
ISL68201
datasheet for more details.
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 may be created.
The ISL68201-99140DEMO1Z is a 6-layer board
demonstrating a compact 17mmx17mm 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 PMBus dongle (ZLUSBEVAL3Z), i.e., USB-to-PMBus™
adapter, and USB cable are included in the demonstration kit.
Intersil's PowerNavigator™ evaluation software can be
installed from Intersil's website and evaluate the full PMBus
functionality of the part using a PC running Microsoft
Windows 7 or 8.
