[31] BUCK: Increased BUCK Hysteretic quiescent current

This anomaly applies to Revision 1, build codes QEAA-C00, CAAA-C00.

Symptoms

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

Conditions

BUCK load current has decreased to below 20 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.
