TMI3257

中压Buck转换器

The TMI3257 is a high efficiency 800kHz current mode constant on-time (CM-COT) control mode synchronous step-down DC-DC converter capable of delivering 2A current. TMI3257 integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. Low output voltage ripple a . High Efficiency: Up to 93%(@3.3V)(2). 800kHz Frequency Operation(2). Up to 2.0A Output Current(2). Low RDS(ON)for internal switches:90mΩ/45mΩ(top/bottom)(2). 4.5V to 18V Input Voltage Range(2). 0.807V Reference(2). Current mode COT control to achieve fast transient responses(2). Integrated int;
