                SGM6033

                4.6MHz, 1A Synchronous Step-Down Regulator
                GENERAL DESCRIPTION

                The SGM6033 is a 4.6MHz, synchronous step-down switching voltage regulator, with 1A output current capability, that delivers adjustable output from an input voltage supply of 2.5V to 5.5V. Using an architecture with synchronous rectification, the SGM6033 is capable of delivering a peak efficiency of 90%, while maintaining efficiency over 80% at load currents as low as 1mA.

                The regulator operates at a nominal fixed frequency of 4.6MHz, which reduces the value of the external components to as low as 470nH for the output inductor and 4.7μF for the output capacitor.

                At moderate and light loads, pulse frequency modulation (PFM) is used to operate the device in power-save mode with a typical quiescent current of 26μA. Even with such a low quiescent current, the part exhibits excellent transient response during large load swings. At higher loads, the system automatically switches to fixed-frequency control, operating at 4.6MHz.

                The SGM6033 is available in Green TDFN-2×2-6L and WLCSP-1.21×0.81-6B packages. It operates over an ambient temperature range of -40 to +85.
