描述
The ISL78236DUALEVAL1Z kit is designed for individuals requiring point-of-load (POL) applications with input voltages ranging from 2.85V to 6V. This evaluation board demonstrates the performance of the ISL78236 low quiescent current mode converter. It is configured to deliver up to 3A of output current on each of its two output channels.
The ISL78236 is offered in a compact 4mm x 4mm 24 Ld QFN package with a maximum height of 1mm. The complete converter occupies an area of less than 5.46cm2. Additionally, the ISL78236 is AEC-Q100 qualified and rated for the automotive temperature range of -40°C to +105°C.
