For even lower current rails, the ISL85412 and ISL85413 are available. Similar to the other devices in the family, they have a wide input voltage range of 3.5V to 40V, integrated MOSFETs (RDS(ON): 900/500mΩ), a bootstrap diode, and internal compensation for a compact solution size. However, the switching frequency is fixed at 700kHz and the soft-start is internally set to 2.3ms. Features once again include enable, power good, and full protection for over current, over and under voltage, and temperature. The result is a simple and robust device for lower current, high voltage rails.
