TMI3252F数据手册Tollsemi中文资料规格书

描述 Description

The TMI3252F and TMI3252TF are high efficiency 600kHz, Constant on-Time (COT) control mode synchronous step-down DC-DC converter capable of delivering up to 2A current with force PWM operation. TMI3252F and TMI3252TF integrate 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 600kHz switching frequency. It adopts the COT architecture to achieve fast transient responses for high voltage step down applications.The TMI3252F and TMI3252TF require a minimum number of readily available standard external components and is available in a 6-pin SOT23-6 ROHS compliant package.
