The TMI3258 is a high efficiency 600kHz current mode constant on-time (CM-COT) control mode synchronous step-down DC-DC converter capable of delivering 3A current. TMI3258 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 CM-COT architecture to achieve fast transient responses for high voltage step down applications.

The TMI3258 requires a minimum number of readily available standard external components and is available in a space saving 6-pin SOT563 ROHS compliant package.
