By this system, when load current changes suddenly, it responds at high speed and minimizes the changes of output voltage. Since it is possible to use capacitors with small capacitance and it is unnecessary to add external parts for system phase compensation, this IC realizes downsizing of set and reducing in the number of external parts. Output voltage is adjustable by user. Maximum current is 10 A. APPLICATIONS High Current Distributed Power Systems such as ・HDDs (Hard Disk Drives) ・SSDs (Solid State Drives) ・PCs ・Game consoles ・Servers ・Security Cameras ・Network TVs ・Home Appliances ・OA Equipment etc. APPLICATION CIRCUIT EXAMPLE EFFICIENCY CURVE VREG 100 90 1 µH LX VFB VREG 1 µF SS AGND PGND VOUT = 3.3 V 22 µF  3 10 nF Note : The application circuit is an example.
