2.5A Regulator with Integrated High-Side MOSFET Demonstration Board


The ISL85403DEMO1Z demonstration board allows for quick evaluation of the ISL85403 synchronous buck or boost-buck controller in the synchronous buck configuration. It is also used to demonstrate the compact size solution for the wide input voltage range point-of-load (POL) DC/DC converter using the ISL85403.
