The TMI3252TH is a high efficiency 1MHz, Constant-on-Time (COT) control mode synchronous step-down DC-DC converter capable of delivering up to 2A current. TMI3252TH 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 TMI3252TH requires a minimum number of readily available standard external components and is available in a 6-pin SOT23-6 ROHS compliant package.
