The TMI3244TF is a high efficiency 550kHz, Constant-on-Time (COT) control mode, synchronous step-down DC-DC converter capable of delivering up to Peak 4.0A current with 1.2V output voltage. TMI3244TF 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 550kHz switching frequency. It adopts the COT architecture to achieve fast transient responses for high voltage step down
applications.
The TMI3244TF requires a minimum number of readily available standard external components and is available in a 6-pin SOT23-6 ROHS compliant package.
