TMI3267 800kHz, 18V, 2.0A Synchronous Step-Down Converter
●The TMI3267 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. TMI3267 integrates main switch and synchronous switch with very low R-DS(ON) to minimize the conduction loss. Low output voltage ripple and small external inductor and capacitor size are achieved with 800kHz switching frequency. It adopts the CM-COT architecture to achieve fast transient responses for high voltage step down applications.
●The TMI3267 requires a minimum number of readily available standard external components and is available in a space saving 6-pin SOT563 ROHS compliant package.
■FEATURES:
●High Efficiency: Up to 93%(@3.3V)
●800kHz Frequency Operation
●Up to 2.0A Output Current
●Low R-DS(ON) for internal switches: 90mΩ/45mΩ(top/bottom)
●4.5V to 18V Input Voltage Range
●0.6V Reference
●Current mode COT control to achieve fast transient responses
●Integrated internal compensation
●Stable with Low ESR Ceramic Output Capacitors
●Over Current Protection with Hiccup Mode
●Thermal Shutdown
●Inrush Current Limit and Soft Start
●Available in SOT563 Package
