TMI3253TH 1MHz 18V 3.0A Synchronous COT Step-Down Converter
●The TMI3253TH 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. TMI3253TH integrates main switch and synchronous switch with very low R-DS(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 TMI3253TH requires a minimum number of readily available standard external components and is available in a 6-pin SOT23-6 ROHS compliant package.
■Features:
●70mΩ/35mΩ Low R-DS(ON) internal FETs
