AT7240

AT7240 500mA, 30V, 2MHz Synchronous Step-Down Converter FEATURES Immense Advance Tech. DESCRIPTION 4.7V to 30V operating input range 500mA output current Up to 93% efficiency High efficiency (>78%) at light load Internal Soft-Start 2MHz switching frequency Input under voltage lockout Available in SOT26 package Current run-away protection Short circuit protection Thermal protection APPLICATION Distributed Power Systems Automotive Systems High Voltage Power Conversion Industrial Power Systems Battery Powered Systems The AT7240 is a current mode monolithic buck switching regulator. Operating with an input range of 4.7V~30V, the AT7240 delivers 500mA of continuous output current with two integrated N-Channel MOSFETs. The internal synchronous power switches provide high efficiency without the use of an external Schottky diode. At light loads, the regulator operates in low frequency to maintain high efficiency and low output ripples. Current mode control provides tight load transient res...
