The ISL68200 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 ISL68200 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
2
C interface.
See the ISL68200 datasheet for more details.
The ISL68200DEMO1Z is a 6-layer board demonstrating a
compact 17mmx17mm 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 PMBus dongle (ZLUSBEVAL3Z USB-to-PMBus adapter) and
USB cable are included with the demonstration board.
Intersil’s evaluation software can be installed from Intersil’s
website and be used to evaluate the full PMBus functionality of
the part using a PC running Microsoft Windows.
