SGM6022 6MHz, 600mA Synchronous Step-Down Regulator
The SGM6022 is a 6MHz, step-down switching voltage regulator, with 600mA output current capability, that delivers a fixed output from an input
voltage supply of 2.5V to 5.5V. Using an architecture with synchronous rectification, the SGM6022 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 6MHz, which reduces the value of the external components to as low as 470nH for the output inductor and 4.7|JF 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 22|JA. 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 6MHz. Its output could be programmed to four different voltages, as well as two different on/off delay times, making it ideal for designing primary supply.
The SGM6022 is available in a Green TDFN-2x2-6L package. It operates over an ambient temperature range of -40°C to +125°C.
