The ISL9440AEVAL1Z evaluation board features the

ISL9440A. The ISL9440A is a a quad-output controller

that integrates three PWM synchronous buck controllers

and one low-dropout linear regulator controller. The

ISL9440A offers internal soft-start, independent enable

functions and integrates UV/OV/OC/OT protection. Its

current mode control architecture and internal

compensation network keep peripheral component

count minimal. Switching frequency of 600kHz

minimizes inductor size while the strong gate drivers

deliver up to 12A to each PWM channel.

The ISL9440AEVAL1Z is easy to set up to evaluate the

performance of the ISL9440A. Please refer to the

“Electrical Specifications” table on page 2 for typical

performance summary.
