TMI3280数据手册Tollsemi中文资料规格书

描述 Description

The TMI3280 is a fully integrated, high-efficiency 2.0A synchronous rectified step-down converter.The TMI3280 operates at high efficiency over a wide output current load range. This TMI3280 adopts the instant PWM architecture to achieve fast transient responses for high step down applications and high efficiency at light loads.The TMI3280 requires a minimum number of readily available standard external components and is available in a 6-pin SOT23 ROHS compliant package.
