The ISL8105BEVAL1Z (8 Ld SOIC), ISL8105BEVAL2Z (10 Ld DFN) evaluation boards highlight the operation of the ISL8105B controller in a DC/DC application. The ISL8105B is a simple single-phase PWM controller for a synchronous buck converter that operates from +5V or +12V bias supply voltage. With integrated linear regulator, boot diode, and gate drivers, the ISL8105B reduces external component count and board space requirements.
