The AIC1592 provides adjustable overcurrent pro-tection threshold from external component, fixed threshold both undervoltage and overvoltage pro-tection. The application circuit just uses one single power supply.
A multifunction pin (COMP) allows external com-pensation for optimum load step response and shutdown. Soft start can also be implemented with this pin to properly sequence supplies.
The AIC1592 is available in space-saving 10 pins MSOP package.
