The TMI3253TF is a high efficiency 600kHz, Constant-on-Time (COT) control mode, synchronous step-down DC-DC converter capable of delivering up to 3.0A current. TMI3253TF 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 TMI3253TF requires a minimum number of readily available standard external components and is available in a 6-pin SOT23-6 ROHS compliant package.
