Automotive High Efficiency Synchronous Buck Regulator Evaluation Board


The ISL78236CRSHEVAL1Z kit is intended for use by individuals with requirements for point-of-load (POL) applications sourcing from 2.85V to 6V. The ISL78236CRSHEVAL1Z evaluation board is used to demonstrate the performance of the ISL78236 low quiescent current mode converter in current sharing configuration. The evaluation board is configured to deliver up to 6A output current with both outputs paralleled together. The ISL78236 can also be used in dual output 3A/3A configuration as well. The ISL78236 is offered in a 4mmx4mm 24 Ld QFN package with 1mm maximum height. The complete converter occupies less than 5.46cm2 area.
