The TMI3286 and TMI3286🧜B are a high efficiency 500kHz, Constant-🧸on-Time (COT) c꧋ontrol mode, and synchronous step-down DC-DC converter capable of delivering up to 4.0A current with ཧ1.2V outpu❀t voltage. TMI3286 integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. 🍃Low output voltage ripple and small external 𒉰inductor and capacitor size are achi𝕴ev🌄ed with 500kHz switching frequency. It adopts the COT architecture to achieve fas🐲t 🍸 transient responses for high voltage step down🔜 &🉐nbsp;applications. The TMI3286 requires a minimum number of readily ava🍸ilable st💛andard external components and is available in an 8-pin ESOP8 RoHS compliant package for good thermal performance.
