The ISL8014A is a high efficiency, monolithic, synchronous step-down DC/DC converter that can deliver up to 4A 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 ISL8014A 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 400mV dropout voltage at 4A output current. High 1MHz pulse-width modulation (PWM) switching frequency allows the for 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 ISL8014A can be configured for discontinuous or forced continuous ope...
