DATASHEET ISL8011 1.2A Integrated FETs, High Efficiency Synchronous Buck Regulator FN9254 Rev 2.00 August 4, 2009 ISL8011 is an integrated FET, 1.2A synchronous buck regulator for general purpose point-of load applications. It is optimized for generating low output voltages down to 0.8V. The supply voltage range is from 2.7V to 5.5V allowing the use from common 3.3V or 5V supply rails and Lithium ion battery inputs. It has guaranteed minimum output current of 1.2A. 1.5MHz pulse-width modulation (PWM) switching frequency allowing the use of small external components. The ISL8011 includes a pair of low ON-resistance P-Channel and N-Channel internal MOSFETs to maximize efficiency and minimize external component count. 100% duty-cycle operation allows less than 200mV dropout voltage at 1.
