                SGM66052

                Efficient Synchronous Step-Up Converter with a 2.7A Switch in UTDFN Package
                 
                Efficient Synchronous Step-Up Converter with a 2.7A Switch in UTDFN Package
                GENERAL DESCRIPTION

                The SGM66052 is an internally compensated, 1.1MHz switching frequency, current mode, synchronous step-up switching regulator, which is capable of generating 5V output at 1A load current from a 3.3V rail.

                This device turns into power-saving mode to maintain high efficiency by lowering switching frequency. With its anti-ringing circuitry damping the charge in parasitic capacitor, it reduces EMI interference significantly. Its output is disconnected by the rectifier circuit during shutdown, with no input to output leakage.

                The SGM66052-5.1 is preset for outputting 5.1V, while the SGM66052-ADJ is output voltage programmable with an external resistor divider.

                The device is available in a Green UTDFN-2×1.5-6L package and operates over an ambient temperature range of -40 to +85.
