The SGM6038 is a family of high power density synchronous Buck converters which are capable of delivering 4A/6A continuous output current from 2.4V to 5.5V input voltage range. The device only consumes 5μA (TYP) quiescent current.
The SGM6038 implements an I2C interface to further enhance the device’s flexibility and ease of use to adapt for various application needs. The device implements auto PFM mode operation to maximize the efficiency at light load condition. At moderate to heavy load, the device automatically switches to CCM operation with a 2.3MHz (TYP) switching frequency. forced PWM operation is also available via I2C programming for low output voltage ripple requirement.
The SGM6038 implements the constant on-time (COT) architecture that incorporates the benefits of fast load and line transient responses and low output voltage ripple, which is beneficial for RF and noise sensitive applications.
The SGM6038 family of devices offers VID option for dynamic voltage scaling (DVS) via the I2C interface, which can adjust the output voltage rapidly to adapt for any changes on the load side. Another variant of the device offers an active-low power good (VSET/nPG) function.
The SGM6038 is available in a Green TQFN-1.5×2.5 -9L package.
