The SGM62118 is a synchronous 4-switch Buck-Boost converter which is suitable for battery operated applications. The device’s programmable light load PFM mode and low quiescent current (18μA, TYP) offer above 90% efficiency in the 10mA to 2A output current range. The output voltage is programmable via external feedback resistor divider.
The SGM62118 can 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 device implements pre-defined mode transition thresholds to avoid undesired toggling within modes to reduce output voltage ripple.
The SGM62118 offers various protection features to improve device robustness such as over-temperature, input over-voltage and output over-current protections. These features can protect the device against unexpected system failure.
The SGM62118 is available in a small Green WLCSP-2.21×1.40-15B package. High integration provides a compact solution with only six external components.
