Isl85009Eval1Z Evaluation Board User Guide
Description
The
ISL85009
is a 3.8V to 18V input, 9A synchronous buck
regulator for applications with input voltage from multi-cell
batteries or regulated 5V and 12V power rails. The device also
provides an integrated bootstrap diode for the high-side gate
driver to reduce the external parts count. The
ISL85009EVAL1Z platform allows quick evaluation of the
high-performance features of the ISL85009 buck regulator.
