ISL8023, ISL8024
Compact Synchronous Buck Regulator
The ISL8023, ISL8024 are highly efficient, monolithic, synchronous step-down DC/DC converters that can deliver 3A (ISL8023) or 4A (ISL8024) of continuous output current from a 2.7V to 5.5V input supply. The devices use current mode control architecture to deliver very low duty cycle operation at high frequency with fast transient response and excellent loop stability.
The ISL8023 and ISL8024 integrate a very low On-resistance P-Channel (45mΩ) high side FET and N-Channel (19mΩ) low side FET to maximize efficiency and minimize external component count. The 100% duty-cycle operation allows less than 200mV dropout voltage at 4A output current. The operation frequency of the pulse-width modulator (PWM) is adjustable from 500kHz to 4MHz.
