The TMI3252SHF is a high efficiency 1MHz, Constant on-Time (COT) control mode synchronous step-down DC-DC converter capable of delivering up to 2A current with force PWM operation. TMI3252SHF 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 TMI3252SHF requires a minimum number of readily available standard external components and is available in a 6-pin SOT23-6 ROHS compliant package.
