ISL8013A

DATASHEET ISL8013A 3A Low Quiescent Current 1MHz High Efficiency Synchronous Buck Regulator FN7526 Rev 2.00 November 17, 2014 The ISL8013A is a high efficiency, monolithic, synchronous step-down DC/DC converter that can deliver up to 3A continuous output current from a 2.8V to 5.5V input supply. It uses a current control architecture to deliver very low duty cycle operation at high frequency with fast transient response and excellent loop stability. The ISL8013A integrates a pair of low ON-resistance P-Channel and N-Channel internal MOSFETs to maximize efficiency and minimize external component count. The 100% duty-cycle operation allows less than 300mV dropout voltage at 3A output current. High 1MHz pulse-width modulation (PWM) switching frequency allows for the use of small external components and the SYNC input enables multiple ICs to synchronize out-of-phase to reduce ripple and eliminate beat frequencies. The ISL8013A can be configured for discontinuous or forced continuous ope...
