USERS MANUAL ISL68200DEMO1Z UG067 Rev.2.00 Demonstration Board User Guide Aug 23, 2017 The ISL68200 is a single-phase synchronous buck PWM Key Features controller featuring Intersils proprietary R4 Technology, which has extremely fast transient performance, accurately 20A synchronous buck converter with PMBus control regulated frequency control, and all internal compensation. On-board transient load with adjustable di/dt The ISL68200 supports a wide 4.5V to 24V input voltage range Configurable through resistor pins and a wide 0.5V to 5.5V output range. It includes programmable functions and telemetries for easy use and Cascadeable PMBus connectors 2 high system flexibility using SMBus, PMBus, or I C interface. Integrated LDOs for a single rail solution See the ISL68200 datasheet for more details. Enable switch and power-good indicator The ISL68200DEMO1Z is a 6-layer board demonstrating a All ceramics solution with SP capacitor footprint option compact 17mmx17mm 20A synchronous buck converter. Transient performance, fault protections, DC/AC regulations, Target Specifications PMBus programming, power sequencing, margining, and other features can be evaluated using this board. V = 4.75V to 14.5V IN The PMBus dongle (ZLUSBEVAL3Z USB-to-PMBus adapter) and V = 1V/20A full load OUT USB cable are included with the demonstration board. f = 400kHz SW Intersils evaluation software can be installed from Intersils website and be used to evaluate the full PMBus functionality of Peak efficiency: the part using a PC running Microsoft Windows. - 89% at 12A/1V /12V OUT IN - 94% at 6A/1.8V /5V OUT IN Related Literature Output regulation: 1V 8mV For a full list of related documents, visit our website I/O capacitor rating: C - 16V C - 4V IN OUT - ISL68200 product page Compact size: 17mmx17mm Intersils PowerNavigator User Guide 2 With or without PMBus, SMBus, and I C Capability Ordering Information PART NUMBER DESCRIPTION ISL68200DEMO1Z ISL68200 Demonstration Board (Items shipped: Demonstration board, dongle, USB cable) 1.0F 4.7F VCC PVCC VIN 7VLDO 4.75 TO 15V 1.0F 0.1F BOOT 2 SALERT I C/SMBus/ SCL PMBus UGATE SDA 1V AT 20A PGOOD PGOOD PHASE EN EN IOUT LGATE VCC 10k NTC 1.54k VCC NTC 0.1F 4 PROG1-4 CSEN CSRTN VSEN RGND SGND PGND FIGURE 1.
