ISL78214

DATASHEET ISL78214 4A Low Quiescent Current High Efficiency Synchronous Buck Regulator FN7551 Rev 2.00 May 12, 2015 The ISL78214 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 ISL78214 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, that can be synchronization up to 4MHz with an external clock, allows the use of small external components and SYNC input enables multiple ICs to synchronize out of phase to reduce ripple and eliminate beat frequencies. The ISL78214 can be configu...
