Description

General part information

ISL8023A Series

The ISL8023A is a highly efficient, monolithic, synchronous step-down DC/DC converter that can deliver 3A of continuous output current from a 2.7V to 5.5V input supply. The device uses current mode control architecture to deliver very low-duty cycle operation at high frequency with fast transient response and excellent loop stability. It has an adjustable frequency from 500kHz to 4MHz with the default at 2MHz (ISL8023A/24A).

TheISL8023integrates 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. The default switching frequency of 1MHz is set by connecting the FS pin high, which allows for the use of small external components.

The ISL8023 can be configured for discontinuous or forced continuous operation at light load. Forced continuous operation reduces noise and RF interference while discontinuous mode provides higher efficiency by reducing switching losses at light loads.
