The GRM2040 is a highly integrated power delivery sub-system SoC device of voltage Buck DC/DC power conversion. It integrates power inductor, power switches and voltage regulation circuit in a proprietary 3D structure. The compact and low profile device is in a LGA package of 2.8mm × 3.0mm × 1.3mm, allowing the system to achieve high density. 

The device has up to 2.0MHz synchronous switching step-down converter. This high frequency device is a perfect solution for compact designs. For the GRM2040, the device operates in continuous current mode (CCM) at light and heavy loads. 

The GRM2040 device has a unique 3D structure that lowers the thermal impedance from the top to the bottom below general lead-framed LGA package. The device structure has significantly enhanced thermal conductivity. Other key features include under-voltage lockout (UVLO), integrated soft-start to limit inrush current at startup, over-current protection and thermal shutdown detection. 

The GRM2040 is available in a Green LGA-2.8×3-8AL package.
