USERS MANUAL ISL8002xDEMO1Z and ISL80019xDEMO1Z AN1817 Rev 1.00 Demonstration Board March 10, 2015 Description Key Features The ISL8002, ISL80019, ISL8002A, ISL8002D and ISL80019A High efficiency synchronous buck regulator with up to 95% DEMO1Z kits are intended for use by individuals with efficiency requirements for Point-of-Load applications sourcing from 2.7V 0.8% reference accuracy over temperature/load/line to 5.5V. The ISL8002DEMO1Z and ISL80019DEMO1Z boards Start-up with prebiased output are used to demonstrate the performance of the ISL8002 and ISL80019 low quiescent current mode converters. Internal soft-start - 1ms Soft-stop output discharge during disable The ISL8002 and ISL8019 are offered in a 8 pin 2mmx2mm TDFN package with 1mm maximum height. The complete 1MHz, 2MHz default frequency 2 converter occupies less than 64mm area. Negative OC protection TABLE 1.
