Product Description

The TCS4318 is a high efficiency 600kHz,Constant on-Time (COT) control mode synchronous step-down DC-DC converter capable of delivering up to 3A current. TCS4318 integrates main switch and synchronous switch with very low Ros(oN)to minimize the conduction loss. Low output voltage ripple and small external inductor and capacitor size are achieved with 600kHz switching frequency. It adopts the COT architecture to achieve fast transient responses for high voltage step down applications.The TCS4318 requires a minimum number of readily available standard external components and is available in a 6-pin SOT23-6 ROHS compliant package.
