描述
The ISL8011EVAL1Z evaluation board is used to evaluate the ISL8011, an integrated FET, 1.2A synchronous buck regulator for general purpose point-of-load (POL) applications. It is optimized for generating low output voltages down to 0.8V. The supply voltage range of 2.7V to 5.5V allows the use of common 3.3V or 5V supply rails and Lithium-ion battery inputs. It has a guaranteed minimum output current of 1.2A and a 1.5MHz pulse width modulation (PWM) switching frequency which allows the use of small external components.
