The ISL85009EVAL1Z platform allows quick evaluation of the high-performance features of the ISL85009 buck regulator.

The ISL85009 is a 3.8V to 18V input, 9A synchronous buck regulator for applications with an 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 ISL850xx sync buck regulators support input voltages of 3.8V to 18V and a wide output current range, offering designers a complete portfolio of devices with high efficiency and reliable performance. For a full list of products, visit the 12V Synchronous Buck Regulator Family page.
