TOLL TMI3252S
The TMI3252/S/T is a high efficiency 600kHz, Constant on-Time (COT) control mode synchronous step-down DC-DC converter capable of delivering up to 2A current. It adopts the COT architecture to achieve fast transient responses for high voltage step down applications. The TMI3252 requires a minimum number of readily available standard external components and is available in a 6-pin SOT23-6 ROHS compliant package.| Part No. | TMI3252S |
