Why Low Quiescent Current Matters for Longer Battery Life

By Avnet Silica


DON’T UNDERESTIMATE THE IMPACT OF QUIESCENT CURRENT
When a power supply is in standby mode, power consumption is defined by quiescent current (IQ), which refers to a circuit’s quiet state, when it isn’t driving any load and its inputs aren’t cycling. Quiescent current, while nominal, can also substantially impact a system’s power transfer efficiency during light load operation.
