TMI3208数据手册Tollsemi中文资料规格书

描述 Description

The TMI3208 is a high efficiency 600kHz, Constant on-Time (COT) control mode synchronous stepdown DC-DC converter capable of delivering up to 5A current. TMI3208 integrates main switch and synchronous switch with very low RDS(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 TMI3208 requires a minimum number of readily available standard external components and is available in a 6-pin DFN2x2-6FC ROHS compliant package.
