TMI3256B2 600kHz, 18V, 6A Synchronous COT Step-Down Converter
■The TMI3256B2 is a high efficiency 600kHz, Constant on-Time (COT) control mode synchronous step-down DC-DC converter capable of delivering up to 6A current. TMI3256B2 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 600kHz switching frequency. It adopts the COT architecture to achieve fast transient responses for high voltage step down applications.
■The TMI3256B2 requires a minimum number of readily available standard external components and is available in a 6-pin DFN2x2-6 RoHS compliant package.
