ISL800xxxDEMO1Z Demonstration Boards User Guide
Description
The ISL800xxxDEMO1Z boards are intended for use by
individuals with requirements for point-of-load applications
sourcing from 2.7V to 5.5V. The ISL800xxxDEMO1Z boards are
used to demonstrate the performance of the ISL80020,
ISL80020A, ISL80015, and
ISL80015A
mode converter.
These devices are offered in an 8 Ld 2mmx2mm TDFN
package with 1mm maximum height. The complete converter
2
occupies less than 64mm
area.
