描述
The ISL8105AEVAL1Z evaluation board highlights the operations of the ISL8105A controller in a DC/DC application. The evaluation board is configured for an output voltage of 1.8V and 15A maximum load.
The ISL8105A is a simple single-phase PWM controller for a synchronous buck converter. It operates from +5V or +12V bias supply voltage. With an integrated linear regulator, boot diode, and N-channel MOSFET gate drivers, the ISL8105A reduces external component count and board space requirements. These make the IC suitable for a wide range of applications.
