ISL8026

ISL8026, ISL8026A Compact Synchronous Buck Regulators The ISL8026, ISL8026A are highly efficient, monolithic, synchronous step-down DC/DC converters that can deliver 6A of continuous output current from a 2.5V to 5.5V input supply. The devices use current mode control architecture to deliver a very low duty cycle operation at high frequency with fast transient response and excellent loop stability. The ISL8026, ISL8026A integrate a very low ON-resistance P-channel (36mΩ) high-side FET and N-channel (13mΩ) low-side FET to maximize efficiency and minimize external component count. The 100% duty-cycle operation allows less than 180mV dropout voltage at 6A output current. The operation frequency of the Pulse-width Modulator (PWM) is adjustable from 500kHz to 4MHz. The default switching frequency, which is set by connecting the FS pin high, is 1MHz for the ISL8026 and 2MHz for the ISL8026A. The ISL8026, ISL8026A can be configured for discontinuous or forced continuous operation at light l...
