DC-DC Step-Down Converter IC
■General Descriptions
SI-8000TM series has 300kHz oscillation frequency, so it contributes miniaturization of a chalk coil. Therefore, it realizes a compact and high efficient power supply together with TO 252-5 package compatible:SC-63 .
SI-8000TM series has the function required for switching regulators and protection circuits such as over-current, and overheating. With only four discrete components, it realizes a high efficient switching regulator without adjustment. 1.5A output current by compact power surface mount package.
■Features
●1.5A output current by compact power surface mount package.
