    Description

    The AIC1591 is a voltage mode synchronous buck PWM controller that drives external N-channel power MOSFET using a 300kHz fixed frequency architecure. This device is capable of producing an output voltage as low as 0.8V. It uses external di-vider to adjust output voltage with the exact right line and load regulation.
    The AIC1591 provides adjustable overcurrent pro-tection threshold from external component, fixed threshold both undervoltage and overvoltage pro-tection. LDO is built in to provide AIC1591 logic power source, and 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 AIC1591 is available in space-saving 10 pins MSOP package.
