The TMI32561 is a high efficiency 600kHz, Constant on-Time (COT) control mode synchronous 𒈔step-down DC-DC converter capable of delivering up 💛to 6A꧟ current. TMI32561 integrates main switch and synchronous switc꧃h with ver🀅y low RDS(ON) to minimize the c🍨onduction loss. Low output voltag💫😼e ripple and small external inductor and capa🏅citor size are achieved with 600kHz swit✱ching 🐼frequency. It adopts the COT architecture to achieve fast traꦆnsient responses for high voltage step down applications. The TMI32561 requires a minimum number of readily avail𒀰able standard external compo𒆙nents and is available in a ESOP8 RoHS compliant package.
