GENERAL DEscriptION
The SGM6022 is a high-efficient Buck switching voltage regulator, supporting up to 600mA output current and fixed output voltage. This device is capable to provide an input voltage supply range of 2.5V to 5.5V. The 6MHz fixed frequency operation allows the use of a 470nH output inductor and a 4.7μF output capacitor.
The SGM6022 operates in power-save mode under moderate and light load conditions through pulse frequency modulation (PFM). The 22μA typical quiescent current and the power-save mode can further improve the system efficiency which can reach a maximum of 90%. The SGM6022 also has excellent load transient response capability. Its output could be programmed to four different voltages, as well as two different on/off delay times, making it ideal for designing primary supplies. The SGM6022 also includes the features of internal soft-start, input under-voltage lockout, thermal shutdown and overload protection.
The SGM6022 is available in a Green TDFN-2×2-6L package. It operates over an ambient temperature range of -40℃ to +125℃.
