[63] POWER: DC/DC does not automatically switch off in System ON IDLE

This anomaly applies to IC Rev. Engineering B, build codes QFAA-BA0, CHAA-AA0.

It was inherited from the previous IC revision Engineering A.

Symptoms

The device will draw current periodically (in the mA range) when in System ON IDLE.

Conditions

DC/DC is enabled and in System ON IDLE.

Consequences

Average current consumption in idle mode is too high.

Workaround
