Description    The FP6373A is a high-efficiency 1MHz synchronous step-down DC-DC regulator and capable of delivering output current up to 3A. The FP6373A operates over wide input voltage range from 2.7V to 5.5V, and integrates main switch and synchronous switch with very low R DS(ON) to minimize the conduction loss.     Low output voltage ripple, small external inductor and capacitor sizes are achieved with 1MHz switching frequency.

Features  2.7V-5.5V Input Voltage Range  Adjustable Output Voltage Down to 0.6V  Low R DS(ON) for Internal Switch (Top/Bottom): 95/75mΩ  1MHz Switching Frequency Minimizes the External Components  Internal Compensation Function  Internal Soft-Start Limits the Inrush Current  100% Dropout Operation  Power Good Indicator Output  RoHS Compliant and Halogen Free  Compact Package: SOT-23-6

Applications  Set Top Box  LCD TV  Tablet  Portable Equipment
