  General Description
¡á General Description
   
    The AA18380 is a single-channel PWM DC-DC regulator control IC that supports low-voltage
    operation. This IC features a low minimum operating voltage of 1.8 V and low current
    consumption, is optimal for use in high-efficiency power supplies for portable electronic
    equipment.


¡á Features

    - Wide operating supply voltage range: 1.8 V to 15 V
    - Stable reference voltage circuit: 1.25V.
    - Low current consumption: Typically 5.5 mA in operation, 1 ¥ìA or less in stand-by
    - Wide PWM output frequency range: 10 kHz to 1 MHz
    - Incorporates a soft start circuit and adjustable soft start time.
    - Timer latch short-circuit protection circuit (SCP).
    - Low input voltage malfunction prevention circuit (U.V.L.O.)
    - On/off control function
    - Totem-pole type output by using an external resistor to set the output current
      (for NPN transistors)


¡á Applications

    - LCD Displays
    - PDAs
    - Digital Still Cameras
    - Hand-held and portable instruments
