ISL8018-Slide4

This is the block diagram of the ISL8018. When FS is connected to VIN, the loop is internally compensated to meet the needs of most applications and the switching frequency is set to 1MHz. The output voltage can be margined by + or – 10% using VSET. This feature is valuable for compensating the IR dropped due to far away system load by increasing the voltage up 10%. VSET can be lowered by 10% to reduce system power dissipation. In addition to these features, the output current can be adjusted to 3A, 5A or 8A using ISET pin.
