Package
The SGM62110 and SGM62111 are 4-switch buck-boost converters with programmable I2C interface for simple configuration of integrated rich features. Synchronous rectification improves system efficiency which is friendly for battery operated applications. In addition, the programmable light load PFM (pulse frequency modulation) mode and low quiescent current (15μA, TYP) offer above 90% efficiency in the 10mA to 2A output current range.
The devices are capable to operate in buck, boost or a novel 4-cycle buck-boost mode when the input voltage is close to or equal to the output voltage. The devices implement pre -defined mode transition thresholds to avoid undesired toggling between modes to reduce output voltage ripple.
Dynamic voltage scaling is enabled via VSEL pin and I2C controlled output voltage registers which allows the device to toggle output voltages based on application needs.
The SGM62110 and SGM62111 implement robust protection features such as over-temperature, input over-voltage, output over-current protections to protect device against unexpected system failure.
The SGM62110 and SGM62111 are available in a small WLCSP-2.21×1.40-15B package. High integration provides a compact solution with only four external components, allowing implementation in a PCB area as small as 39mm2.
