AT2721

AT2721 8-40V,3A Synchronous Buck Converter FEATURES Immense Advance Tech. DESCRIPTION Wide 8V to 40V Operating Input Range Integrated 140mΩ Power MOSFET Switches Output Adjustable from 1V to 25V Up to 93% Efficiency Internal Soft-Start Stable with Low ESR Ceramic Output Capacitors Cycle-by-Cycle Over Current Protection Input Under/Over Voltage Lockout 3A Output Current The AT2721 is a monolithic synchronous buck regulator. The device integrates two internal power MOSFETs, and provides 3A of continuous load current over a wide input voltage of 8V to 40V. Current mode control provides fast transient response and cycle-by-cycle current limit. An internal soft-start prevents inrush current a turn-on, This device, available in PSOP-8 package, provides a very compact solution with minimal external components.
