The TMI3253SH is a high efficiency 1MHz, Constant-on-Time (COT) control mode synchronous step-down DC-DC converter capable of delivering up to 3.0A current with 1.2V output voltage. TMI3253SH 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 1MHz switching frequency. It adopts the COT architecture to achieve fast transient responses for high voltage step down applications.

The TMI3253SH requires a minimum number of readily available standard external components and is available in a 6-pin SOT23-6 ROHS compliant package.
