The TMI3255TF is a high efficiency 600kHz, Constant on-Time (COT) control mode synchronous step-down DC-DC converter capable of delivering up to 5A current. TMI3255TF 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 and force PWM operation in steady
state to achieve fast transient responses for high voltage step down applications.
 
The TMI3255TF requires a minimum number of readily available standard external components and is available in a 6-pin SOT23-6 RoHS compliant package.
