STI3452HFI规格书详情
描述 Description
The STI3452HFI 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. STI3452HFI 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\u0002COT architecture to achieve fast transient responses for high voltage step down applications.
