ISL8011IRZ-T

ISL8011IRZ-T 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 ISL8011IRZ-T 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 1.2A. The ISL8011IRZ-T offers a 200ms Power-On-Reset (POR) timer at power-up. When shutdown, the ISL8011IRZ-T discharges the output capacitor. Other features include internal digital soft-start, enable for power sequence, overcurrent protection, and thermal shutdown. The ISL8011IRZ-T is offered in a 10 Ld 3mmx3mm DFN package with 1mm maximum height. The complete converter occupies less than 1cm2 area.
