Another addition to the ISL801x and ISL802x family of regulators, the ISL8018 was designed to support greater than 6 A load current requirements. The input and output voltage range is similar to the previously mentioned solutions, except the IC will support a continuous load of up to 8 A. The ISL8018 has all the features common with the ISL801x/2x family such as PFM/PWM mode, synchronization to external clock and PGOOD/EN, as well as the features found in the ISL8016. It has the programmable output current limit to provide over current protection to systems with various load requirements, adjustable switching frequency from 500 kHz to 4 MHz, selectable output voltage margining of ±10%, bidirectional SYNC to eliminate or reduce beat frequency when using multiple ICs, adjustable soft-start and start-up in pre-biased load for a monotonic start-up, and a negative current limit. It also has excellent efficiency up to 97%.
