[29] BUCK: Increased BUCK Hysteretic quiescent current

This anomaly applies to Engineering C, build codes QEAA-BA0, CAAA-BA0, QEAA-BC0.

Symptoms

BUCK quiescent current increases during Hysteretic load currents below typically 5 mA.

Conditions

BUCK load current has decreased to below 5 mA while in Hysteretic mode.

Consequences

BUCK quiescent current increases by approximately 300 µA.

Workaround

Prompt read or write over TWI from host below a load current of 5 mA.
