The TMI32560 is a high efficiency 600kHz, Constant on-Time (COT) control mode synchronous step-down DC-DC converter capable of delivering up to 6A current. TMI32560 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 and force PWM operation in steady state to achieve fast transient responses for high voltage step down applications. The TMI32560 requires a minimum number of readily available standard external components and is available in ESOP8 RoHS compliant package.
