The TMI3286 and TMI3286B are a high efficiency 500kHz, Constant-on-Time (COT) control mode, and synchronous step-down DC-DC converter capable of delivering up to 4.0A current with 1.2V output 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 inductor and capacitor size are achieved with 500kHz switching frequency. It adopts the COT architecture to achieve fast transient responses for high voltage step down applications. The TMI3286 requires a minimum number of readily available standard external components and is available in an 8-pin ESOP8 RoHS compliant package for good thermal performance.
