The STI3452HF is a high efficiency 1MHz current mode constant on-time (CM-COT) control mode synchronous step-downꦐ DC-DC converter capable of delivering 2A current with force PWM operation. STI3452HF integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. Low output voltage ri🦄pple and small external inductor and capacitor size are achieved with 1MHz switching frequency. It adopts the CM-COT architecture to achieve fast transient responses for high voltage step down applications. The STI3452HF requires a minimum number of readily available standard external components and is available in a space saving 6-pin SOT563 ROHS compliant package.
