The STI3452HF is a high efficiency 1MHz current mode constant on-time (CM-COT) control mode synchronous step-down 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 ripple 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.
