Overview
DC/DC Step-Down Converter IC SI-8000TM Series September 2005 ■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.
