This system responds rapidly to sudden variations in load current, thus maintaining the fluctuations in the output voltage to a minimum level. The system does not require external components for phase compensation. Together with the use of capacitors with small capacitance, this IC realizes downsizing of the set and reduces to a great extent, the number of external parts required for the system. Output voltage is adjustable by user. Maximum current is 6 A.
